If your going about 40mph and set cruise or push on the gas a little and let off the rear end pops and kind of bounces, this is the only vehicle I have that has done this could be bad U-Joints or something else?

See my profile and recent posts.

Make sure you haven't been driving in 4X4. On hard surfaces.(And Didn't know it)

I am guessing you do not know how to check your "U" joints.

If you have 2WD you have 2, 4WD you have 4

Get your rig level and chock the wheel(s). In front of and behind. No can rolley either way!

Put you rig in neutral. Vehicle OFF. Crawl under

1 "U" joint is near rearend on drive shaft other 1 is at transmission/ tranfer case on the drive shaft.

4x4 is reversed, but at the frontend driveshaft.


Grab the driveshaft side of the joint with one hand, and the differential side of joint with your other hand.

With "Opposing Force" with you hands, See if there is ANY MOVEMENT between the 2 yokes and at the center "+". Also look for damage at the caps on the ends of "+" (4 caps)

If there is damage or movement, its time for new "U" Joints.

I am a CJ guy and do not know your rig, your front wheel drive may not be set up like a Jeep or older 4X4s.A manual would really assist you, for this and future problems. Maintenece and trouble shooting. Step by step repairs.

This may not be your fix----this is the 1st place to start

Keep me informed

Love, Turddog
