How do you take out the drain plug on the rear differential of a model 20 from a 79 cj5? Looks like you have to put some type of insert in it and turn. Wondering if there is any special thing i need .
owned 1978 cj-7 since 1979
401 .030 over- full floating flat top pistons
crower solid cam 292 dur .500/.510 lift
th-400 / 4500 stall
Dana 44 5.13 gears

best ever 11.669 @ 112.33 mph on 33 x 10.50 slicks and 4" lift in the 1/4 mile on all motor no spray - 7.358 @ 93.03 mph in 1/8 mile
if your taking off the diff cover too you should toss those torx head bolts for a hex head bolt...i had to use a bolt extractor on almost all mine after i broke two torx sockets...you can get zinc plated or stainless steel bolts for a nice touch also...and screw the cork gasket...cork is for bobbers and wine stoppers
I'm thinking of putting the synthetic gear lube in my CJ7 1978 axles when I change the oil, etc., and wanted to see if anyone here has an opinion. Am I just wasting money, or is there a big benefit down the road.
I used that royal purple stuff from our host. Crazy expensive but it sure quieted everything down. I used it in the entire drivetrain. The captain's right about the cork, get rid of it if you go to a sythetic.....it will leak.
Wow what a simple task. I just used some 80w 90 gear oil when I changed mine. Synthetic is good but if you wheel you rig every day or weekend then stay with the regular stuff because I am sure that you will have to change more often . Good luck.
