Hey All. 2001 Jeep WJ 4.7L with 128K on it. When i shift from P to D, or D to R, or P to R, or R/D to P i get a pretty loud popping noise and the jeep kinda jumps a bit. However, if I am going to park it and I put it in N, pull the e-brake until it catches, then Put it in P, it shifts like butter with no noise, lurching, or popping...any ideas?

Transmission mount, motor mount(least likely), or failing rear u-joint.

I'm leaning towards a u-joint, just dont know which one or ones. If I were to get them at advance, which should I get if I want to replace both in the rear? Or should I do all 5 while I'm doing it?

I've had mine on a Jeep Grand Cherokee for a year and been happy with them. Luk Schaffer makes a nice slotted cross drilled rotor (this may help keep them cool and prohibit warping) for not a ton of money. I think they're called Black XD Series.

Tell him to make sure that his calipers aren't frozen when installing new pads or rotors, better yet replace them or rebuild them if in doubt. This will help to insure longer life and no rotor warping.
