The Monte has developed a very bad vibration in high gear. Changed driveshafts and the problem seemed to lessen temporarily, but it's back as bad as before. The driveshaft is straight. Dad can barely hold the shifter back in 4th as he crosses the finish line. We are taking the tranny apart to see if the mainshaft is bent or ???. Can a ring gear be out of balance? We are sending the clutch and disk away to get balanced. Axles ???.
Any help would be appreciated as we're really scratching our heads on this one. Many thanks in advance!!

Just random thoughts, but 1, Make sure rear hasn't moved (string-measure both sides, center of front whl. to center of back whl.) 2, Pinion bearing going bad, or something moved inside rear? Good luck....WJ

Several years ago, I had a front wheel/tire out of balance at Scribner that caused my vision to blur so bad that I could not see the scoreboards.
It shook everything in the car. I had Joe Archer re-balance and cleared it up. |

Rear bushing in tranny or main shaft bearing.

Had a similar problem years ago. I had the drive shaft rebalanced, changed the bushing in the trans tail shaft housing, and also had the front and rear wheels rebalanced. Problem was still there, bad vibration about the last 300' of the track. Ended up breaking the trans case across the bell housing. I put a new Dedenbear trans case in the car and the problems was still there. By this time the rear tires needed replacing and bingo the problem went away. Smooth as glass with the new tires. Before this problem started the car had sat in the garage for two months while freshing the engine. I had neglected to put the car up on jack stands and I guess the rear tires got flat spots. Won't make that mistake again.

Hey mike when we first got the cavalier done we had a terrible vibration in the steering from the 1000 ft on ,we checked everything, to make a long story short we had a bad set of front tires how we found this out jason took them to a tire shop in north kcmo that balances big tires like for FWD trucks it is different than conventional spin balancers it has wheel of some sort that spins on the outside of the tire and thats how we found out the tire wasn't round from now on we always take them there to get mounted and balanced . this might not be your problem but keep that in mind for the future ,don't trust the track balancers were you buy your tires we had both front and rears checked and they told us they were ok ! good luck chris
