vibration/rumble below floor on 99 jeep grand cherokee

Asked by Oct 21, 2013 at 07:47 PM about the 1999 Jeep Grand Cherokee Laredo 4WD

Question type: Maintenance & Repair

Just bought this rig and no matter if i'm stopped, park, neutral, reverse or drive there is a
grinding and vibration under the car. I cant pinpoint the exact location, but to me it seems
as though its right under my seat. I thought the t-case, but took to my mechanic and he
drove it really quick and said NOPE it wasnt the t-case. He didnt have time to check it out
so i'm hoping someone on here has an idea. Please help. I'm trying to sell this thing.

Might be the exhaust is up against something causing the vibration or one of your motor or trans mounts are shot.

The trans mount sounds right?

Thank you guys for trying. All it was? The cover for the t-case was hit while someone was off-roading. It made the car have an awful vibration when on. Bent the cover back to good and BOOOM! Sound was gone :)
