Ok i was just wondering if anyone else has had a vibration after installing gears. I put in new richmond 4.10 and now have a vibration only on deceleration and and kinda at the floating point but not under acceleration. Any ideas?

Thanks

Sounds like severe backlash misadjustment, lack of bearing preload but most likely the driveshaft is installed wrong.

I once had a ring pop off the ujoint and when I bolted up the DS it was slightly off center. Shook like mad.

Check the driveshaft install.

 

Here's a bump, as I just had 4.10's installed and my car is doing the EXACT same thing. And I mean EXACTLY.

 

I've got the richmond 4.10s and if you have a steel driveshaft that is definitely part of your problem. I am now running an LS1 aluminum driveshaft with mine and it still vibrates some but not nearly as bad as it did. If I had to do gears again I would go with a brand other than richmond.

P.S. I also have a poly trans mount so that could be why mine still vibrates some.

 

Mine has strange gears and I believe an LS1 ds. However, even if it was the stock DS, I've had it at 100+ many many times prior to the gear swap and it never vibrated.
