Questions: I have a 1951 CJ3A with a leaky transfer case and none of the shift levers will stay in gear and fall back to neutral when moving. I have to bungee cord them into gear to get them to work properly. Is it time for a rebuilt or new transfer case or is this an easier problem to fix?
Question By: Gavin on Dec 7 2020 8:54 PM
Sounds like it. Your poppet balls and springs and shift forks are for sure worn.

Questions: Do you offer rebuilt transmissions and transfer cases, or just brand new? What's the price difference if so? My wife towed mine on a uhaul before i could disconnect the drive shaft and melted My tranny at least. Do you think it harmed the transfer case also?
Question By: Kyle on Apr 6 2015 12:00 AM
It all probably needs to be gone thru. These are all new internals in original cases.
