    Default Poly rack bushings

    I've never changed a rack and pinion rack bushings, but I'm pretty surprised how big the poly bushings are (Energy suspension 7-18102).

    I don't have a picture, but when I rest the clamps on top of the rack with bushings, the clamps are about 1cm away from touching the crossmember where the rack rests.

    So I guess I just have to torque down the clamps pretty hard?

    By the way, I made sure I had the thinner bushings on the driver's side and the thicker ones on the passenger side.

    They're snug fitting compared to the old rubber. Be sure to use plenty of the lube that you get with the kit, it'll creak later on if you don't. Here's what helped me the most, Z Tech Tips Suspension (AtlanticZ.ca) || | | | | | | |

    Did you verify that the bushings are completely down in the receiving grooves on the rack? When I did my poly, the bushings were not a very good fit and I had to shave down the inside corners on the bushings to get them to sit well against the rack.

    Here's the details if you haven't seen it already: http://www.classiczcars.com/forums/s...ly-refurb.html

    Does the slit in the bushing close up before you clamp it?


    Remember, the bushings are supposed to be tight as that's what keeps the rack locked in place. There's not supposed to be any play and the poly should be compressed some upon assy, but if those bushings don't fit down in the slots right, there will be too much crush and the bushings will deform in directions you don't want.

    Thanks for the tips!

    I don't want to have to carve them out more (poly is a PITA), but it is good to know that others have had the same issue.

    I bought new rack bolts when I did the suspension rebuild on my '72. The new bolts were slightly longer than the originals. I put just a little silicone grease on the metal straps and made sure I tightened them down evenly. In the end I had no issues getting them installed.
