Occasionally when I bring my 98 150 to a stop I feel a rubbing klunking sound that seems to be coming from my driveshft. At first I thought it was my rear brakes, but when I checked it the brakes wereOK.

 

Have you checked the U-joints?

 

Take a look at the slip joint

 

Thanks for your help. You wouldn't think you would have to check for this type of problem when the vehicle is still new.

 

there a tsb for cab mounts needs tighting to a certain Lbs. torque that causes a clunk noise that seems to be from the rear end
go to your dealership and have them run oasis on your vechile for the tsb i saw it today

 

I have a 98 f150 SC 2wd and I've had that problem too. Ford tech told me the slip yoke didn't have enough lube from the factory and they replaced it with the drive shaft. Seemed to solve the problem, but now I get a vibration at exactly 60mph and the new tires didn't correct that. Don't know what to do now it out of warranty.
