    i have an 01 sierra i have a leveling kit AAL and 285 75 tires letting you know cause i don't know if this has something to do with my problem since it started after i added this stuff. on to the problem. sometimes when i get on the gas from a stop there is a horible clunk as soon as, if not a split second after it has started rolling. it almost feels as if there is play in the drive train but im not sure since it doesn't do it all the time i checked the rear driveshaft no play checked the drive shaft to the front and there was play but i wasn't sure if there is supposed to be if it isn't in fourwheel drive if anyone can make since of what i have typed and give me an idea as to what to do to check for the problem id appreciate it as im not in a financial position to even take it to a mecanic to figure it out im pretty confodent in being able to replace parts but if the job is to big ill have o wait till i can get it somewhere thanks in advance

    Its a quarterly thing for me.... Go to GM and by thier stuff, its called "Special grease" its really expensive, like $40 for a little container and pull the drive shaft out, put a finger full on it and put it back together... give it a little to work itself in and your good to go! No more super annoying clunks

    hate to sound like a jerk cause i really appreciate the help but is the special grease thing real cause it kinda sounds like a left handed monkey wrench or a peep hole for a sliding glass door.

    Nope, its real. Drill a hole in the yoke and tap it. Insert a zerk fitting and grease it when you service it. That will take care of it. Or, put a rubber ball inside the yoke.

    I have used ceramic or synthetic grease. Can use almost anything.

    My truck had a clunk and it was the rubber that come out of a tranny mount or a transfer case mount. I dont remember. My mechanic fixed it and its been fine ever since.
