Rear End does not line up ???

[duff33]

I am installing a rear end from moser, following the directions, installed lower arms, then shocks, but the drivers side upper arm just does not line up. I must be doing something wrong. The radius of the arm interferes with the rear end which will not allow the bolt to pass through because the holes just do not line up. I have switched arms drivers side vs passenger side, even with out the arm bolted to the chassis, it still has interference and will not allow the bolt the pass through ???????729207292172922

Try dropping the lower arms. You can then rotate the rear around the one with bolt in to get other to line up. Then reinstall lowers (which are easier to line up). That usually works for me.

Thanks for the suggestion. The upper control arm did not fit even when it was not bolted to the chassis. I went to ff5 this morning and spoke with Dan, it turns out that if you are going to run a Moser rear with 4 link the upper control arms have to be modified. Moser is casting the rear ends now and have beefed up the ears over factory specs. That causes the interference. One side of the drivers side arm has to have the side radius made smaller and the web has to be relieved so that it does not rub on the top of the ear on the rear.72961
