Default Control Arm Bushings Replaced

Finally got around to replacing the upper control arm bushings.
I did the lower ones about 3 yrs ago but wanted to wait on the
uppers to minimize the complexity of finding any squeaks.
(the replacements are polyurethane)
No real issue to speak of. Took 4hrs. Time to go out and test drive it
in a few hours.
I used Energy Suspension for the replacements.

Amazing difference in tightness.
Worth it for sure. The old rubber bushings were soft
like sponge rubber.

Now for new shoes for her and an alignment.
Then I'll be ready for the driving season.

Did that last winter along w new ball joints, upper and lower. This winter, replaced sway bar ends, tie rod ends F/R, and rear trailing control arm bushings. Much tighter steering, perceptibly flatter cornering. I actually can step down the FX-3 setting.

I checked ball joints. Very tight still and coming up on 100Kmi.
By going after one thing at a time I hope to isolate on what needs
attention and what doesn't.

Next is sway bar but looks fine and the tension can be adjusted.
Hubs are good and tie rod ends are good.
I may replace the center caps on the wheels though.

Scott,

My ZR has 125k+ so I follow the "while you're there" rule.

I follow the "what to tell people with actual experience" rule.
It goes back to Engineering 101 at UNL 43 yrs ago.
The best solution is the most cost effective one.
Not that I haven't shotgunned solutions in the past (bulk replace) but
when you have the time and inclination to go for what has
actually failed, why not?

I think because mine is not exposed to moisture AND
pot holes......... the ball joints are still tight/stiff in the sockets.
I was a bit surprised at the rubber bushing though as soft as they
were.

Can't wait for new shoes on the car. New rubber is the best!!!!

Poly is the way to go.
Did my '93 (LT1) a few years ago and major improvement on handling.
Definite difference between the '93 and the Z.
Want to do my ZR1 in the next year or so.
