Most likely you need a new strut
broken transmission mount there is a front left, rear left and a center mount
cause you might not of put tighten the tire when you replaced it . or your rim is bent, did you hit a curb?
A bad universal joint is one possibility.
Possible bad front end part.
check your front marker light or it is in your steering wheel or bulb is bad
I had a similar problem with my 2004 Jeep Grand Cherokee and it turned out to be my front sway bar bushings and front sway bar link. The sound was a large clunk sound when I went over bumps. After I got it fixed there were no problems.
Worn trans or diff parts. If it gets worse, have it looked at.
what would cause the ADVTRAC OFF light to remain on on my 2005 ford explorer
Chances are it is an oxygen sesor. An OBII code reader should tell you if it is the front or rear sensor. I replcaed the front O2 sensor on my Explorer last fall. Easy job too!!!
The simplest thing to check would be the universal joints on your drive shaft. See if you have any play in any of those universals. The springs in the center of the clutch disk could also be out and cause a clunking. MGB's also have thrust washers in the differential that wear out and cause a clunk in the differential.
A bearing that has gone bad. A universal joint that has worn out allows play in the differential gear.
