M38A1 U joints

[Casey B]

1953 CDN Jeep. Took it for another short drive and can here some not a lot of chattering from underneath even when coasting and out of gear. i suspect it's the U joints.

Anyone have a present day Part # for thes and are all 4 the same.

Also the tranfer case lever for high and low range when pushed all the way forward is just barely engaged so if it is nudged backwads even slighty another sort of chattering occurs. Is this an adjustment issue or is it just worn...?

Thanks Casey
