Need a lil more info...are you running a stock rear end? Does it feel like its bouncing around?

stephen · April 7th, 2009, 03:14 PM

The oil is supposed to be changed at 100K miles. You might try that.

its a stock rearend with an automatic transmission and when im leaving a light or leaving the driveway it feels like its trying to shake my car apart

goren813 · April 7th, 2009, 05:06 PM

Try the oil, if that doesn't do it the gears may be damaged... have a shop inspect them and if need be it's a good excuse to get some 4.10's and t-lok.

Also check for a bad u-joint.

forget having a shop check em, if your going to change the fluid you can inspect them while the cover is off, dont you have to remove the cover to do that?

what kind of oil goes into the stock rearend is it a sspecial kind of oil or just regular oil

stephen · April 8th, 2009, 12:06 PM

It uses 90 weight hypoid oil. Any parts store will know what you need. You don't need the additive for a limited slip rear axle.
