Radial Wabble Problem

[Ven302]

After checking the rear shocks, (your hand is not a shock dyno) You need to really look over your rear end, brackets, gussets, welds everything with a fine tooth comb, something in your car is probably flexing, or maybe cracked, I had the same problem. Also which radials and on what size rim? I found that a 13.25inch radial wants a 14" rim and the 14" wants a 15" rim. Email me @ venjr@aol.com and I can tell you all of my troubles, which by the way are gone now.

rear shock adjustment issue as told from those who have had this problem with their radials

Honestly i don't have the car right here in my view. (its and hour away from me) so im just gonna guess that they are 14X32 Hoosier Radial. We are gonna end up putting new struts and shocks on it for the simple reasoning of not knowing how long they have been on the car.(Whats the best bang for the buck on the shocks and struts?) I have checked all the brackets 4 link bars the rear chassis itself with a fine tooth comb i honestly don't see anything wrong but there is obviously something there that isn't happy.

I agree with the shocks. If they are adjustable, they are set too loose-or worn out.

I had the same problem with 2 of my cars. My 81 Malibu front end would wiggle around as I let off at the top end. It got downright scary. Tightened up the front shocks to fix it.

My 64 Chevelle would bounce the back end down track, then got real bad as I applied the brakes at the top end. People said the back tires looked like ping-pong balls bouncing. Rear shocks were toast. Replaced them and it fixed it.

Don't skimp on shocks. Get a good (read expensive) set of double adjustables and they will last through many passes and adjustments.

Good luck!

Put some snubbers on the front end so the front end can only go down so far. You will be amazed at how much that will help.

Greg, i do believe the car has snuggers on the front. Any other suggestions??

In your description of the problem you left out many of the possible contributing factors. What is happening to the vehicle is the suspension is unloading upon deceleration and finding weak points in the structure or geometry. The radials are a major contributor to the reaction of the suspension, but not the initiater. If you have a four-link suspension, you may have a problem with your wishbone flexing, bending, or just loose in the mounting.Check to ensure that all connecting points of bars are sufficiently secured and not allowed to "wobble", thus keeping the car in a straight line until the suspension collects itself.
Additionally, make sure the front suspension reacts equally in separation and compression and is totally fluid in movement.
