Chevy & GMC Vans

dropped by a friends shop. up on the hoist .. u-joints looked okay. checked rear diff level, also good. diff fluid was done when I got the van and royal purple was used at that time, it's only had about 15000kms on it at most. he also remarked that it could have been the brakes kind of sticking then releasing.

either way, I'm going to try and change the fluid and filter in the tranny this weekend if the weather cooperates

i was thinking when i first saw this thread about the drum brakes sticking then someone mentioned it. our 95 used to do it never did fix it before it got retired though so can't say what exactly caused it
