I hate to double post but I had this in the Suspension/Chassis section and there were a lot of views and no responces in the past 2 days. So I am going to try here now...

I am getting a strange vibration and not sure if it is wheel hop or not...

My entire suspension is stock minus removal of the front sway bar, and the car only has 79K miles...

For the past few thousand miles, about a year, the rear end and rear suspension has been noisy, with a lot of squeeks and creaks while driving or jacking up the car. In this same time frame the rear end started going out and doing single wheel burnouts and spinning on the street. The gap in the wheel well remains about the same with about 4.5 inches from the top of my stock wheel to the bottom of the wheel well so I don't think that springs are sagging...

Recently I have developed this strange vibration when I accelerate hard, and after the 1-2 shift. It feels like I am driving over the rumble strips on the side of the highway. I think this is wheel hop and also due to the single wheel slipping. The strange part is I have felt wheel hope in a lot of other cars and it has never felt like this, it was always a jerking chirp-chirp-chirp and you could feel the rear actually hop.

So is this a strange type of wheel hop or is my rear actually almost completely gone, and causing this?

And before anyone asks/comments, I know the rear is going out, but I was trying to figure out what this vibration was. I don't really have the money to throw at the car and hope that was the cause, I know I need suspension and a rear, but no way can I afford both right now. It would also suck to spend $1000 for rear suspension to find that the vibe was the rear telling me it was about to give up completely, or vice versa, spend $3k on a rear just to find I stll can accelerate because the the suspension is toast...

 

Even in a non posi rear end your car should not feel like it's on egg shells. I would suggest that you take a look at the stock rear lower control arms. The rubber bushings could be extremely worn. I would replace these with heavy duty tubular rear control arms to eliminate any type of wheel hop. Also take a look at the lower panhard rod, this also has rubber bushings and is subject to wear and can cause the side to side motion you described. As for the vibration F bodies have had their problems with the drive shafts. Remove yours and have it rebalanced or try to find a used aluminum one and have it rebalanced. Good Luck!

 

good thoughts on the suspension parts, I will check them out. But as for the d-shaft it isn't the problem...

The vibe is only on acceleration and in situation where it feels like the wheels are spinning, like from a start or on shifts, that's why I think it might be wheel hop. I have had the car up over 100 today and the shaft wasn't causing any sort of vibrations...
