Car Forum / Jeep / January 2006Draining front differential CJ3B
Is there a drain hole somewhere on the bottom of front differential? I can only find the fill plug mid way up the cover. If that's it, how do you change the fluid? Thanks. Yamash They figured you like the smell and feel of old gear oil so you have to pull off the cover to change the fluid. It is a good idea anyway so you can get any dirt and gunk out.

It keeps the cover from falling into the oil pan when you pry it off. Also it's a good idea to change the fluid after a short run. Warmer fluid drains more effectivly.  SignatureDougW And be sure to use a good sealant like this: PERMATEX® ULTRA BLUE® No Leak RTV Silicone Gasket Maker http://www.caswellplating.com/permatex/permgasketmakers.html to seal the differential cover after you scrape off all the old gasket material and clean it really well.

If it has a drain, I still would open it the first time to make sure it isn't full of gunk.

The front one does not have any drain in bottom. At least this one doesn't. I'm yanking the cover off and cleaning it out. Maybe I'll find the damn thing then. Then on to knuckles, wheel bearings, finish brakes, etc...fresh gas and it fired right up. yamash > http://www.billhughes.com/temp/dana25drain.jpg It's understood. > God Bless America, Bill O|||||||O [quoted text clipped - 11 lines] >> Jan/06 http://www.imagestation.com/album/pictures.html?id=2115147590 >> (More Off Road album links at bottom of the view page) There is no drain plug, you have to remove the cover to drain the diff. > Is there a drain hole somewhere on the bottom of front differential?
