Z31 steering rack help
My parents have a '86 Z that's a part-time rebuild project. The suspension is complete except for a problem with the steering rack bushings. The old set was worn out enough to warrant replacement, so we ordered a set of poly rack bushings from z31parts.com.
As it stands, the steering rack is able to shift itself left to right nearly a half-inch. It mostly happens at very low speed but it can happen on moderate corners at highway speed. Assuming we can't order the original bushings from Nissan, we're considering either adding shimming/bolstering to the steering rack clamps or finding some solid bushing inserts. Any helpful word would be appreciated. Thanks. |

Have you sent an email to Jason about this? There is a thread about the concerns about the rack movement. Gary and Jason have worked very hard to provide the ultimate in customer service. Here is a link... Z31Performance.com • View topic - poly steering rack bushings ETA??

The clamps you are looking for are NLA. Nobody reproduces them. You will have to find some that are used or at a pick and pull scrapyard. Your best bet is to put up a WTB ad on the z31 forums.

Been there done that
I bought new Nissan bushings ($100). Did the same thing. Did you rebuild your suspension, i.e. new ball joints, tie rod ends? I had completely rebuilt the front end, shocks, bushings etc. Unfortunately my 85T is not running (2 years). So I can't remember if it went away or not. I think it did. And I attributed the slippage to stiff new parts causing the rack to move no matter how tight I tightened the clamps. I also thought there might be a slight difference in the diameter of the rebuilt rack I purchased but I had returned the old core (original rack) so I couldn't check to see. Sorry if this is no help but I do believe the slippage subsided with breaking in. But it sure was an uncomfortable feeling.

Like a lot of people with NA I had this problem.
The 87 had a thinner rack bracket on the driver side. There was play with the Nissan bushing and the MFP poly bushing. Since I already had an extra turbo rack, I ordered Turbo Bracket Bolts and a Turbo Bracket. The part for the bracket has been superseded and is the same as the thin bracket on my NA. I scored a early model turbo bracket on the forum, swapped to a turbo rack and installed the poly bushings. When torque down there is zero rack movement. Not good. |
