Polyurethane bushings
In another example of the ?while you are there? maintenance of our ZRs, I replaced the rear wheel bearings on my 92. Its been a while and I kept hearing a slight scraping sound coming from the right rear. Put the rear end up and checked for play and yeah left side rocked a bit, left rear was solid. So ordered two Timken bearings from RA. Once I had wheels off, I could see that the rear sway bar end link bushings were shot. So ordered a set of the Poly bushings from Energy Suspension. Fortunately they came in time for me to do the whole job at the same time. Takes longer the older u get! 🤣🤪 Getting the old ones out took a bit but they were clearly the originals.
Long story short, I can definitely feel that the rear suspension is ?crisper?. The increased stiffness is noticeable. Several years ago I did do Poly bushings all the way around but not the rear sway bar or the rear diff. Wondering if anyone else has noticed an increased ride stiffness if you have done this upgrade.

Re: Polyurethane bushings
Recently just installed a rear lowering kit w/ poly bushings on my 94. Felt like it tightened things up back there on mine as well. Ironically I think mine needs a right rear wheel bearing too.

Re: Polyurethane bushings
Hans,
Took a bit m. Turns out I had one of the bar links reversed as well. Took it out for a spin today. Ride is stiff but manageable and corners flat.
