69chevelle69 Jan 10th, 04, 2:02 PM can anyone tell me where to find the torque specs for the spline bolts holding the upper control arm to the frame? also i am curious about the alignment shims are they supposed to be the same amount on both control arms or are there different amounts? Does every car have different amounts is it something specific to your car or a model thing? thanks in advance andrewb70 Jan 10th, 04, 2:47 PM I am not sure about the torque specs, but I can tell you about the shims. They will vary from car to car as well as from side to side. They are put there by the alignment shop to give you the proper caster and camber settings. So there is not "correct" number. Take it to a reputable alignment shop and they will install the right number of shims for your car. Andrew 69chevelle69 Jan 10th, 04, 11:59 PM I read a previous forumn that guys had assemblied the front end without shims and then very carefully drove it to the alignment shop and said it is easy for them at the shop to add shims as needed. To do this im assuming the bolts through the shaft would have to be brand new splined bolts so you could loosen the nuts off without spinning the bolt to add shims? You couldnt get to the bolt head without flipping the upper control arm. I ask because right now im assemblying the front end and obviously when i put the disc spindles on the bj i obviously cant flip the control arm to hold the bolt. Should i try to align the bj myself and use my shims with my old bolts or get new proper bolts in the shaft and let the shop take care of it when it goes in? thanks for all your expertise! andrewb70 Jan 11th, 04, 1:50 PM The bolt that holds the upper control arm is splined. So after its all put together, you can just loosen the nuts holding the control arm and add the shims as needed. If the bolt is spinning while you are trying to loosen the nuts, then the splines have stripped the hole. Did that answer your question? smile.gif Andrew 69chevelle69 Jan 11th, 04, 3:27 PM yes it did thanks, but what can I do now with a stripped hole make sure my shims are perfect before I put the disc brakes on i guess graemlins/clonk.gif sinned Jan 11th, 04, 3:45 PM Put a new stud in the frame hole, they are still available. If that doesn't fix it, get access to a MIG and tack in place. Your alignment price will be affected and the attitude of the alignment tech will also change depending on whether or not all 4 of those stay in place while turning the nuts. Take it from an alignment guy, if those studs spin, he won't be in a good mood while working on YOUR CAR :D | ||
