Things that go clunk in the night....

Postby Pengyou [OP] » June 20th 2016, 5:26pm

When I get my van going, whether forward or reverse, there is a very slight pause and a slight clunk. In days of yesteryear, when I had a Scout, that noise meant that my u-joints needed attention. I made the mistake of taking my 'store to a national chain shop - we can call it FireRock, just for the sake of anonymity :banana: , and they told me that I needed new spider gears in the rear diff and wanted $900 to buy and install them..even showed me where a couple of the teeth had been chewed a little bit. I quickly took my baby 'stro away from those people and brought it home. It is still driving - working fine - but experience says that tiny clunks usually become bigger clunks, and when they get to be really big clunks, they sometimes run for president :)

From my limited scope of knowledge, it could be u-joints. I also believe that there is a clutch in the transmission that is used when putting the car into motion (F or R) that might make this sound. Any other options? How to divine which area is the culprit?

Does the clunk happen from P, when putting the van into D or R ? Sounds like harsh garage shifts. Sometimes the transmission valve body spacer plates get worn out and the check balls get stuck.

Not when shifting into into gear int gear but when the van starts moving.
