So i have a 98 durango with the 5.2l 4x4 and i had the rear end completely rebuilt 18k ago (all new bearings, ring gear pinion etc....) it has the 3.93 LSD diff. recently after driving on the freeway for 5+ miles when i stop on the off ramp and go to take off even slowly there is a shudder in the rear of the durango it feels like driving over a cattle guards slowly. any ideas.

 

Pull the diff cover of and do a inspection for wear and tear and any damage

just changed the fluid it was black and really thin so i changed it and put in the bottle of friction modifier. i will take it out in the morning and try it. i hope its not the diff because im 3 months past the warranty.

 

it quit doing the shudder when i get off the ramp. now it does it at slow speeds in parking lots. so im lost with whats going on with it.

 

Have you checked your tires back there? It's just a thought but I just replaced the rear tires of my Cadillac because of a similar problem. It started with a shudder at high speed, then it started at low speeds as well. It turned out that I had a steel belt that had separated inside the right rear tire. It might be something as simple as that.

 

i hope its not the tires there a week old with only 200 miles on them. im thinking it could be a u joint or the drive shaft. i made a appointment on friday with the local mechanic because im lost with what it could be. the u joints are tight i pryed on them with a bar with the the vechile lifted up.

 

if it started around the time you got the tires id take it back to the tire place and complain that it started bc you probably got a faulty tire, they should replace it free of charge
