Just wondering if anyone has any information about the rear springs?
Now that the front struts are good and the rear shocks are good the rear springs squeak or creak rather when jacking up the car, or going over a bump. Is there spring insulators that they sell for the rear springs or a way to keep them quiet?

 

Yes there are. If that's whats making them squeak. Also might want to check the axle bushings too.
Check for broken springs also. Rare, but we have seen a couple posts about them being broken.
The parts should be readily available at a parts store or online.
#5 is the bump stop or jounce.
#6 is called the isolater or seat.

 

Ohh, thank you.
And no my springs are good. :)

 

Hey were are you getting those schematics? They would be nice to get a hold of.

 

I get parts diagrams from various websites and save them to my computer.
That one above looks like it came from GMpartsdirect.

Most of the genuine GM parts websites seem to use the same set of diagrams.

 

Looks like the jounce is $30, seems expensive? Or is that the price? No one makes aftermarket ones?

 

Not really that expensive compared to ones for other cars/trucks.
I bought some for my Dodge pickup(the rubber bumper jounce on the LCA.)
Just the rubber part was $18 each.

 

Try other sites, many GM parts sites offer huge discounts. Try eBay.

 

Ok...
So I have now changed the shocks all around, the two front hub and bearing assemblies, and the rotors but was told they were warped just because there was shaking but I had them measured with a caliper tool and one was perfect and the other was off by like a thousandth of an inch, which is still good right? And they have exact same brake wear on both sides.

What could it be now? Car still shakes when braking down a incline.
??? Tie rods ??? Ball joints ??? Rotor is indeed in need of resurfacing ???

Please help thank you! :)

 

Any worn part that allows slack or "play" in the suspension could be the cause.
LCA's, tie rods, steering column just to name a few.
Just have to figure out which one is your problem.

Just for giggles. Have you tried swapping tires around ? Fronts to backs. Backs to fronts.
Tires have been known to mimic suspension problems.
