Question......When ever I am going 25-30 mph, 3rd gear, when there isnt any torque on the rear it kurckunks....like when I coast in any high gear at a slower speed..it kurcklunks till I get on the gas a little....Does this sound like the rear needs to be re-shimmed?
i had a similar problem and it was due to the pinion angle being off from when i had my upper and lower control arms installed. after it was set properly the noise was gone
