    Yeah, thats some crazy torque. Since I'm not replacing my bushings I'll knock the bolts out of the shaft, rotate it to locate the ball joints to the rear and reinstall. Gotta pick up some 90* Zerks too. We'll see if I still have enough room to grease them after I shift the uca towards the rear. Then it's off to find a decent alignment shop. This has been a highly educational thread.

    Sorry to dredge this up out of the archives, but that's what you get when the search function is used;). So, in reading above, the factory spec is to center the shaft in the control arm, but several comments suggest off-setting the shaft to the rear. Is there a general consensus on how much to off-set the shaft? Thanks.

    At least half turn.

    You want at least 3* positive caster, 4* is better.

    One thing I should have mentioned, caster setting is for P/S, on a manual steer, 2.5* should be max.

    It doesn't look like I'm gonna get anymore than half a turn before the zerk fitting contacts the shock tower. I'd have to do without the fitting or persuade the tower to move over a little :smash: if I want to offset the shaft anymore.

    And bushings get torqued to 60 lb ft, not 175.

    LOL.. no doubt. Those fine threads would never hold that much torque before shearing anyways.

    Also good to be cautious when engaging those first few threads too because I've seen guys cross thread them and just drive them on till they bite anyways. Probably another reason why I don't like many people working on my rides.. ASE cert'd or not.

    My son nearly did this, but noticed that it looked "crooked" before putting the ratchet to it.
