If camber is out of adjustment you will see uneven tire wear, if the camber is too negative for example then the tire will wear the inside tread. I'll replace everything in the front end if I have to but I … Now, not all alignment shops are bad, some do know the drill with lowered trucks and are quite good. The control arms, top and bottom yellow parts, are usually adjusted by cam bolts or eccentric-washer bolts to effect camber and caster changes. If camber is out of adjustment you will see uneven tire wear, if the camber is too negative for example then the tire will wear the inside tread. If you need more positive camber, thread them in. Yes Bob,this issue is concerning the 53 210.I always make sure I use the proper forum for my questions.But I would rather ask the question here,than on the VCCA forum,too many people just telling me to read the shop manual over there with no real useful info.Not always,but most of the time.

Step 1 Put on the safety glasses and place the vehicle on the alignment rack. The pin also has an eccenctric section in the center that the clamp bolt bears against to set camber by rotating the pin parallel to the car centerline. Usually, all four wheels will feature some negative camber, and a vehicle will tend to pull to the side that has the most positive camber.Camber may need to be adjusted if your usage scenario demands better cornering performance. To move the control arm inward (add negative camber), remove an equal number of and thickness of shims from both bolts. When getting a wheel alignment, what should camber be set to for performance driving? Camber is not good for tire wear, Camber doesn’t improve directional stability, Camber adversely effects braking and acceleration. Just another reason you can do this in your garage! If you are doing your own alignment or just getting it close before you take it in, always make the toe adjustment your last one. TOE IN/OUT Back in the old days, before radial tires and power steering, alignment values were a lot different. These bolts can most … now that i have added my 3.25" lift my camber seems to be off. A slight amount of negative camber can increase the amount of lateral grip a car has at the limit, though too much negative camber can result in uneven tire wear, reduced grip, and premature tire failure. 5. CAMBER AND CASTER ADJUSTMENT NOTE: 4X4 (LD) SUSPENSION HEIGHT MEASUREMENT MUST BE PERFORMED BEFORE AN ALIGNMENT. You will be adjusting the camber where the ball joint adjoins the upper A-arm. If you are the spirited driver from the camber tutorial, you could benefit from some of the handling properties of positive caster. Then loosen the lower heim joint by loosening the nut of the lower control arm. Before we look into what negative Camber is, we must first look at what Camber is. Most off road vehicles will benefit from a negative camber degree resulting in a slightly wider width on the track surface which will benefit in the turns and reduce roll-overs. Refer to Trim Height Inspection in Suspension General Diagnosis. Glad you asked! Adjusting Camber is an easy process on most RC’s and is very easy to complete in just a few steps. The A arms are not equal and there is no way to adjust … There are several methods to adjust camber, depending on the vehicle and its suspension. If camber is different from side to side it may cause a pulling problem. This was because of tires actually changing shape and altering the physical dimensions of the front end. Because of this most rear wheel drive vehicles use some positive toe-in, which allow the wheels to run parallel to each other at highway speeds. Moving the upper arm out gets you more positive and moving it in results in negative camber. Also the rear camber looks pretty extreme. Positive Camber: Negative Camber: Adjusting Camber? The cart I'm working on is a 2008 precedent. The reason that any driver might want this though is that it does have a noticeable impact on your car's handling abilities. That is why we often see the sports car having a negative camber. Check out the caster illustration to help understand this alignment characteristic. Small metal shims are needed to do any camber adjustment. For street guys a little toe-in is probably the best choice. You will need to loosen the lock nut on the ball joint before adjusting. Before adjusting the caster and camber angles, jounce the front bumper three times to allow the vehicle to return to normal height. How much camber is too much? (This is discussed on the coil spring page). Increased toe-in will typically result in reduced oversteer, and improve high speed stability, but too much and you get an unresponsive, thick feeling. Running negative camber will increase the acceleration and top speed of the car. For example caster tended to be negative because at highway speed the dynamic caster resulted in a positive value, with a corresponding near zero or very slight negative camber. On rear wheel drive trucks they push the front end down the road causing the control arms to “deflect” rearward against their bushings. It only takes 1° of negative camber on a street vehicle to create this disadvantage. So what happens if caster is out of alignment? So moving the upper control arm in or out (relative to the frame) is how camber is controlled. Threading the ball joint into the A-arm (toward the wheel) or retracting it (away from the wheel) moves the angle outward or inward, respectively. My left rear tire is straight up and down, maybe 1/4 negative camber and my rear passenger side is bout 3/4 inch negative camber. Look at it this way, you've used a grocery cart, notice the rear wheels and how they are mounted slightly behind the vertical steering axis, or a motorcycle front fork slopes back providing positive caster. Yes Bob,this issue is concerning the 53 210.I always make sure I use the proper forum for my questions.But I would rather ask the question here,than on the VCCA forum,too many people just telling me to read the shop manual over there with no real useful info.Not always,but most of the time. You may have spent more hard earned money on wheels and tires than your lowering kit, easy to do, so make dang sure your not wasting your dough after getting your “look”. Increased toe-out reduces understeer, and improves “turn in” when cornering. You must adjust the nuts to bring them closer to or farther from the frame of the car if the camber is out or in respectively. In fact if you are trying to fine-tune your alignment it is better to adjust caster than camber. Tighten the upper control arm and replace the tire. http://chevy.oldcarmanualproject.com/shop/1949_53/... YOU TELLM 'HELLS A COMIN" I'm bringin it with me. Negative caster being like … Some of these vehicles are bagged (equipped with air suspension) so that when parked, the body can be brought down lower than would be possible if driven.In general, lowering a car creates additional negative camber because of the nature of suspension design and wheel movement. Most often, camber measurement can be corrected with a camber bolt. Camber is the angle of how perpendicular your wheel sits on the ground. Spindles do not have any effect (good or bad) on the alignment. I added another 1/2" to the right just to see if it straightened it up but it still had 3/4" difference from the top of the rim to the bottom. We have covered most issues you can encounter when it comes to alignment of lowered trucks. Camber and Caster are adjusted on the same pivot pin on the outboard side of the upper control arm. Just like high performance tuning of engines, you can do a high performance “tuning” of your suspension with alignment. Follow the machine's direction to determine the alignment … Hi all. If this pivot angle is leaning toward the back of the truck it is positive caster, and, of course, if the angle is rotated toward the front of the truck, it is negative caster.
