1985 Jeep cj7

No No No dont do it will destroy the tcase. Having been woking on jeeps since 1977 and rebuild more than i wish to talk about. Biggist problem was the chains wouls streach easy way to check put in drive slam the gas pedal to the floor if you hear a big bang as if something comming thru floor chain bad.we had a special tool to check chain still have one in my tool box. They were veryeasy to replace in the jeep. Not sure if you can still get parts for these,havent done one in years.
