Increasing toe-out will typically reduce understeer (front tires sliding when going into a corner). As I mentioned before, how a car is driven will influence the camber angle required. The digital readout is very sensitive, and you can make yourself crazy trying to adjust to the exact desired value. Figure 3. If a gearbox steering is used, loosen both nuts on both adjuster sleeves (right and left). Rotate each adjuster one full turn and then bounce on the suspension. But, that is not an option for many enthusiasts. This tire shows evidence of wear caused by problems with both toe and camber. It will also fight the lateral force of the road pulling sideways against the bottom of the tire. Next, move to the rear of the tire, and measure to the same spot at the rear of the tire, let’s say we get 65 5/16 inches. Popular models include Chevelle, Camaro, and Nova. "Y" Body (Front) 1) Lift front bumper 1.5" (38 mm) and let settle. Here is a quick video on how you can adjust your front wheel toe alignment yourself and save a bunch of money. Heavy-duty steel shims are a must-have for any front end alignment. Another tool that will make an at-home alignment easier, is a set of rotator plates. Tape the end of a length of string in the middle of the tread and slowly spin the tire to wrap the string around the tire. If this axis is straight up and down, the car would have neutral caster. If your car feels like it is too easy to steer and even wants to “wander” while going down the road, this could be too much negative caster. To accomplish this, the tire must properly inflated to eliminate the “bulge” of the tire as it rests on the ground. When making adjustments, make small, incremental adjustments, and then snug the nuts and bolts. Alignment specs given by manufactures typically have a camber-error range of plus/minus 0.5 degrees, meaning if the camber is within 0.5 degrees of the desired value the car is considered to be within spec. Again, can a big-chain store understand what your car needs? If you are planning to get one of these relatively inexpensive alignment kits yourself, I personally think it’s a good investment. The Chevy Cruze debuted as the replacement for the Cobalt. … Front-end alignment is important, but it also carries with it a new set of terms. This is caused by friction. 71-72 A-Body Cars will use outer tie rod ends from a 73-77 A-Body. It also improves stability while driving straight, but at the cost of increased steering effort. Most shop alignments will be the thrust type. On the outside and under the hood, the Cruze is a big upgrade from the Cobalt. Figure 4. . Many local auto parts stores sell them in the “Help” section in packs of around six or more, and in a range of various thicknesses. The spec in the computer usually has very little caster and they will set the alignment to … Once they set in, the only way to reverse them once the problem is repaired, is to grind off tread irregularities. By rotating the offset shaft in the control arm when you install it, you can push the tire towards the fender (positive camber) or in towards the motor (negative camber) to fix the wheel alignment. If you plan on racing into corners, you’ll probably want to customize your alignment. If you are spending your weekends in salvage yards, you can also grab a handful while you’re grabbing other parts. But, you do need to at least get it at least close to specification. Toe is the easiest measurement to obtain. An increase of positive caster will increase steering effort and straight-line tracking. Some parts stores might rent you a camber-measuring device that uses a magnet to secure it to the front hub. Caster is the axis at which the wheel pivots or turns. A carpenter’s square can also be used if you have one large enough. Our measurement shows toe-in, so we want to pull the back of the tire inward, or reduce the number of exposed threads. Caster is a stability angle, measured in degrees. During negative-camber conditions, each tire develops camber thrust when the vehicle is driven straight ahead. Settling on an appropriate camber setting that takes into account the driver’s aggressiveness will help balance treadwear with cornering performance. Two ways to notice your car has camber-alignment issues are: the vehicle pulls to one side (low tire pressure can also cause this) and uneven treadwear across the tread. Optional Ride Height Tuning Kits are available for use with our Pro Series Springs or ­'standard type' springs to raise the ride height if desired. If you don't, they will most likely use the spec in the computer. This is because the vehicle is fighting the excessive angle of the tires. Lift the front end up enough to place your turn plates down under the front tires. Buy Alignment Parts - Front - Steering & Suspension online from NAPA Auto Parts Stores. For instance, cars that see normal highway use can follow factory guidelines. If you plan on doing any driving where you need to increase the handling capabilities of the car, a slight inward lean (negative camber) of about 1 to 1 1/2 degrees is ideal. Typical toe-in specs vary from 1/32- to 1/8-inch, depending on the vehicle. However, they can be heavy and cumbersome, and decidedly not cheap. If working on a car with rack-and-pinion steering, loosen the lock nut on both outer tie rods. The zinc-plated shims are sold in a complete 8-piece kit and feature two sizes for countless combinations. Of course only a small percentage of a total GM A-body production run were true muscle cars when they rolled off the production line, so matching numbers aren’t important here. Having too much toe – either in or out – can cause instability at high speeds and substantially increased tire wear. The 0.135" and 0.63" shims can be stacked to achieve the required alignment specification. Use the torpedo level or a protractor as in the images above to determine the inward or outward slant of the tire. All rights reserved. Left: Shims come in different shapes and sizes, but by necessity, all look similar to these. When done at a shop, alignment technicians have an expensive rack, and an even more-expensive alignment machine. In all honesty, if you follow these directions and get your toe measurement to within a few degrees, camber to within a degree of spec, and tighten everything properly, you shouldn’t have to worry about ruining your tires or new suspension components while driving to the local alignment shop. Right-center: Move up the tire and measure again. If the top of the tire tilts in, the vehicle is experiencing negative camber. As you rotate the adjuster, keep an eye on how many threads are exposed. Use the protractor to measure the angle of the horizontal gap formed by the small leg and the ground. I've been thinking about making some angle measuring tools - nothing fancy, for camber I was going to cut a straight 1x2 16 3/8" long with a set screw in one end. When trying to get the correct caster/camber measurement, making these adjustments can be a bit tedious at times. Overloading the vehicle or a weak or sagging rear spring will affect caster. Chassisworks GM Spindles A-, F-, AND X-BODy FORGED SPiNDLES ('67-72) Chassisworks series of forged A-, F-, and X-body spindles directly replace the OEM components from GM vehicles ranging from 1967-1972 (some models later). In reality, all three of these wheel alignment terms deal with geometric angles and basic measurements: Caster: Caster is the backward or forward tilt of the spindle as you look at … This angle is measured in degrees by comparing an imaginary line (vertical plane) running through the upper and lower ball joints. The toe setting is typically used to help compensate for rubber suspension bushing compliance while the car is moving. This requires four alignment heads, and aligns not only the front wheels, but the rear wheels. Bounce the front and turn the wheels to settle the suspension, then lower the tires onto the turn plates. . Left: Wrap the tire with a piece of string. It will also improve high-speed stability and cornering. It keeps the steering wheel from turning while adjusting toe. Again, make sure the tire pressure is adequate. Adjusting a vehicle’s toe-angle can also alter its handling characteristics. The first step in making sure that you are truly "reading" the alignment is to take the "run-out" of the front wheels. Figure 2. © 2020 Power Automedia. As far … Where you get them is irrelevant, but they are necessary for aligning the front end of your car.

If you do this and can't get the recommended settings, you have a bent frame or badly worn suspension parts). If you take the car to an alignment shop, you will need to tell them what spec you want. The irregular wear pattern, called feathering, is caused by an excessive toe in condition. The car was pulling to the left instead of tracking straight, one sure sign the alignment was askew. . You can also measure sidewall to sidewall if that would be easier. When making these adjustments, have someone hold the steering wheel centered, or use a rope that is tied around the steering wheel and through the door frame to keep it from moving while measuring and adjusting toe. Repeat until you get the adjustment you are looking for. However, with the increased negative camber, a reserved driver’s lower cornering speeds would cause the inside edges of the tires to wear faster than the outside edges. Measure dimension "J" from bottom of rocker panel to floor. If you don’t have one of these, a bungee cord or rope can be used to secure the steering wheel. If you can find one, carefully follow the directions to calibrate and use it. Since finding an old-school alignment shop is getting harder and harder, why not do it yourself? Car handles great.

Right: Control arm with shims installed showing how they cause caster and camber to adjust. This is best described by the following: If your car encounters a bump that only causes one tire to lose grip, the other tire’s negative camber will push the vehicle in the direction of the tire that lost grip. Greased Repeat 2 more times. When we did a dry fit before painting, the hood to fender body lines were uniform down each side of the bed but the gap down each side of the hood was about 1 1/2 inches wide. Positive caster also increases tire lean when cornering (like having more negative camber) as the steering angle is increased. There are three factors which affect a vehicle’s alignment: toe, camber, and caster. Probably the most produced of all the muscle cars, the GM A-bodies were made by every GM brand except Cadillac and GMC. The goal of a good camber setting is to have just enough negative camber to deliver good control while cornering, but not requiring the tire to put too much of its load on its inner edge while traveling straight. In order to properly set camber, you’re going to need a few tools. $7.49. Underneath, however, the two cars have similar setups.

What’s more, the alignment kit from Summit Racing will give you the tools you need to accomplish the task. These are OEM NOS looking; not like what front end . When tightened, bouncing helps the suspension settle. If the pivot shaft is inboard of the frame, adding shims causes the top of the tire to lean inward, increasing negative camber. To adjust camber on most cars, you will add or remove shims which are located between the upper control arms and frame, or adjust an eccentric bolt. Set it against the tire as such and check the bubble. When two shims (one from each bolt) of the same thickness are installed or removed, camber is adjusted.
