Let me know if you feel the tail-wiggling symptoms.

After the Whiteline differential bushing install the rear feels a lot more firm,positive,and planted to the ground. I would definitely replace your differential bushings because it is more of a question of when they will fail? No wiggling symptoms at all. Yes,with all the differential bushing kits available definitely do it right the first time and don’t screw up your installation I would just hate to have to do it twice. If my hands are free I would help out the Z community with a differential bushing installation.

I would say it's your combination of tires. Not the diff.

Too many differential bushings available at a low enough price,,,to even consider half azzin’
& squeezing silicone/glue into a rotted rubber cavaty.
Almost be like removing differential drain & fill plugs...then pumping grease in diff from bottom until it escapes from ck. port???
If you don’t have proper tools/skills,,,I’m sure there are members on forum who would lend a hand to perform proper fix.

I have Eastwest coming to the house to change his diff bushing. He wants me to install the SPL bushing with the Z1 cover.

Really? All mine just dropped snug in place. The lower pieces at the rear of the car needed a tap with a small dead blow and some light lube but went in fine.

The one guy who pm. ed me was having troubles. Told him to spray some lube in the bushing and on the insert.

So out of the Whiteline or the Z1 set of rear diff bushings which ones are the least noisy? And which are easier to install?

z1 poly do not noticeably increase sound or vibration. I can't speak for whiteline.

I have installed 2 SPL bushing kits and JL's Z1 poly bushing kit. The SPL diff bushing was easier to install. There really isn't much difference in noise and vibration between the SPL and the Z1 bushing kits.
