wheel hop/hard vibrations

[95camaro]

Hey guys, I recently took my 95 z28 out of storage and from a 30 drop, the tires spun but their also seemed to be some sort of wheel hop/bucking. This was very brief followed by the car pulling hard as usual. Any thoughts? It definetley did not do this in the fall

only time I had wheel hop issues was when I needed new rear springs....

Tell us about ur rear suspension and tires?

^^Agreed, wheel hop is a product of bad LCA angle which won't change much just by sitting or the shocks no longer being able to control the rear end. I'd put my money on worn out shocks if I had to take a blind guess.

Hey guys thanks for the replies, the diff was down about a quart of oil. I topped it off and the issue was all cleared up.
This is why you don't change your diff fluid at 2am when you've been working for 12 hours

It created wheel hop from low fluid?

I think the posi was kicking in and out, causing one of the tires to try to spin, then grab, then spin, etc

Weird never heard of that happening but, as long and your issue is solved!

My thoughts exactly.

That should not have anything to do with wheel hop.

Hey guys I got a quick question...I have bad shutter and vibration upon takeoff. I know it's not the clutch because it doesn't do it in reverse. I am ordering new shocks and springs here in a few weeks but it is almost unbearable so I am gonna check my diff fluid as well. Anyone ever heard of low fluid causing this problem?
