Radial Wabble Problem
 

Question for all you super stock guys and gals. Im new to this whole super stock thing and i am driving for a cpl great guys outta northern indiana. and i made a few passes in the car this yr and we have come to conclude we have a radial wabble issue. the question i have is if we go to dbl adjustable front struts will this cure the problem?? right now the car has single adjustable strange struts. with dbl adjustables on the rear. This car supposively never did this with byass tires just with the radials. If the struts are the problem whats the best bang for there buck? any input will be greatly appriciated. Thanks

well my thinking here is that it doesn't do it going down the track, its after i lift at the finish line. then it looks like the westcott's. and its really really bad. if you don't have a death grip on the wheel it will snap the wheel right out of your hands.

Aaron,

What kind of tires were they ? I know several other racers who had the same problems with M/T
radials last year.. But, I think the problem was corrected by M/T...I never heard of this problem with Hoosiers...... Maybe its the tires and not the car, you might want to try another set of radials....Good Luck,

Sounds like too much caster in the alignment. Try checking the caster curve at different points of the suspension travel.

I have only heard of the bigger radials doing this. The smaller(9-10") dont do it. I think the tire pressures have an effect on the severity of the wobble.

Put the old tires back on, If it still does it.
Check the rear shocks...
It really sounds like a rear shock.

Re: Radial Wabble Problem
 

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!
