Rear Suspension Pictures - ZR-1 Net Registry Forums

QB93Z · 02-03-2010

SecondChance asked me to get some pictures of high-mile rear tie rod components. The issue is to track down a noise from the rear end of his '94 ZR-1.

Here are some pictures for you (from a 104K mile 1993):

Are the left and right tie rods connected in the center housing, or is it just a pivot point for angular movement?

I guess I need one of you "batwing shiners" to come over and help me clean under my car.

Hey Jim,

I have a set of electronic sensors we can put on to different parts of the rear to see where the noise is coming from

Now I see on your 90 you have solid/stock camber braces. My 90 has adjustable ones just like the tie rods that you can adjust the camber in or out. I was told that they are after market and were not stock.

That sounds like a tool I need to see in action.

We used to use equipment like that on the submarines.

It is actually called a Wireless Chassis EAR Electronic Stethoscope

works great for finding noise

When we are done with the snow we can get together and give it a try

OK.. I see some newer spring insulators and some parts that reflect a 100K+ mileage ZR (my hat off to you for that mileage). Not knowing the exact nature of the "noise from the rear end" my comments deal with deteriorated seals of the axle tie rod to diff carrier assembly and axle tie rod outer sockets.

The obvious problem of lube leakage and possible seal failure would allow for the contamination of the tie rod diff carrier assembly which would cause 'noise' with suspension movement. Here is a 2400 mile ZR of the same part in your first picture>>

And the axle tie rod out socket insulator looks hardened and worn...again compare to a less mileage ZR>>

Regardless of the final determination of noise source would recommend appropriate replacement of worn parts...at 100K+ one would say it is time

Earlier C4s had grease zerk fittings at the outer rear tie rod end. I can't remember if the inner ones were greasable, but you should be able to find the earlier replacements.

Polished, eh? Why you suspension polisher!
I will track this down. Just repace a piece by piece if worst come to worse. I figure it's about time to replace these bushings and joints anyway.
