I have a 2005 chevy silverado crew cab 4X4. Does anyone have any info on the nickel plated slip yoke part number or where i can get it, or a way to permenetly fix the rear end clunk. I've greased it but it comes back way to quick. I tried calling the dealer and all they say is grease it. BSPlease help it's driving me nuts

 

Hey garr58, I have an '03 Silverado and since i bought it a year ago, its done it from day 1. And YES it does drive ya crazy, knowing GM is aware of the problem, since the beginning and won't do a damn thing about it. So, if ya find a solution, let me know as well. Thanx, Jim

 

I have this clunk too in my 03 silverado. What is supposed to be greased and what exactly is the noise from? I thought I had a u-joint going. I just had the torsion bars cranked up to raise the front and some of the creaking noises subsided but the clunk bothers me.
Thanks, Rick.

 

Unbolt the drive shaft, slide it out, grab the U-joints firmly and wiggle and shake the sh*t out of them. There shouldn't be any play in either of them. You might have a grease fitting on one or both U-joints. If so grease em. Throw a glob of the stickiest grease you got into the slip yoke, (about a silver dollar-sized amount tops). Finger it around like it was the girl you used to date in highschool and throw it back together. Smoke a cigarette if you got one.

 

Its the slip yoke the part that comes out of the tranny to the drive shaft. I've taken mine out several times and lubed the splines, it comes back in like 2000 miles. Also is it good to keep plumping grease in there? I've seen TSB's for older model chevy's that say replace the slip yoke with a nickel plated yoke. I'm trying to find out if theres one for my 05.

 

are you guys talking about the rear driveshst or the front? i have a 2005 gmc sierra slt 4x4 crew cab that has this clunk under light throttle usually from a light take off on 1st- to 2nd shift. they dont have grease fittings on the yokes to grease them?
