Funny Chirp noise when i start and stop
 

Hello,

I have just reciently bought a 1999 GMC sierra 4x4 Z71 extended cab with 103,000 miles on it. It is a beautiful truck... My only issue so far is that whenever i start or stop kinda quickly i hear a funny chirp type noise coming from what seems to be the front driver's side. It doesnt seem to be a suspension noise cause it doesnt do it when i go over bumps or if i swerve just when stopping and starting off kinda quickly.... any ideas? ( it sounds sort of like brakes grabbing hard squeak/chirp, but its not the brakes cause it does it when i start off from a stop also....... i wish i knew how to better describe the noise)

thanks guys
Mike

ok i think its the yoke that goes into the transfer case......... where do i go about getting the nickel plated replacement yoke?

that is only a universal joint on the drive shaft, quick fix

had the saME PROBLEM. itis the yoke going into the tr. undo and pull it out of the transfer case, put a handfull of grease where you pulled the yoke from.

how do you permanately fix the problem.....is there a new yoke or something? where is the slippage, in the splines......can this problem lead to otheres?

There is a TSB on this. You need a new nickel plated driveshaft spline. Packing the spline with grease is a temporary fix at best.

If it was in the back it could be the leaf springs rubbing together. Jack it up and put grease in between the leafs. Was told that today by a reliable mechanic.
