Grinding Noise in Back (Upon Acceleration)

[93mazdanavajo]

I haven't been here for awhile, but I'd appreciate it if you guys could help me out on this.

Not always, but sometimes when I accelerate (from a complete stop) I can hear/feel this grinding noise in the back. It's not extreamly noticable but I can tell it's not normal.


Thanks guys.




P.S. I'm installing a 3" body lift tomorrow. I'll try to post pictures next week.

Ummm... you say from a complete stop... how long does it last?

I'm not a pro on this at all, but I'll suggest either the brakes, the bearings, or the differential... Someone else should have a better idea though...

It last maybe 3 seconds...and then it's absolutely fine, and it doesn't happen every time.

Its your universal joints.

Where are those located? How much are they to replace? And how do I do it? I would really appreciate it if you guys could help me out on this one. Thanks!

Theres two on your driveshaft, one near the transfer case and one at the differential. I just did mine yesterday, and is fairly simple to do. The how-to in the link is a great right up. It also is pretty cheap too.

p.s. - it may be slightly different since you navajo, i'm not sure though.
