Wink How to: Drain your rear differential

I'm sure this is a no brainer for most, but I figured I'd make one any-way.

Things you'll need
  • 13mm Socket
  • Torque wrench
  • Appropriate RTV
  • Butter Knives
  • Scraping tool
  • Appropriate differential fluid
  • Beer(s)
  • Something to catch all the old Differential fluid

Step 1 Start loosening the nuts on the cover


Step 2 Once they are all loosened, start taking the bolts out.


Step 3 This is the fun part, getting the housing off, I used butter knives to break the 15+ year old RTV seal



Step 4Once the seal is broken, get ready for the great mud flood-have an oil pan ready to catch all the fluid


Step 5 Take a second to inspect the innards of your differential, look for anything abnormal.


Step 6 Take a break, you deserve it.


Step 7 Clean off all the old RTV from the housing and the differential it's self. (I "forgot" to take a picture of that).

Step 8 This is all optional, but I decided to wire brush and repaint the housing, the lady even came out and made my paint job more awesome.

This Coors is for you WF =)


I think this was great


All done and clear coated, looks good in my opinion. (the lady did all the art work)



Back to the process....
Step 9 Apply the Rtv to the housing of the differential and let it sit for about ten minutes, then start putting the cover back on, socket wrench them down first, then apply the torque wrench (I believe it was 25lbs for mine).


That's all there is to it! I waited 12 hours (according to the RTV recommendations) before I added the fluid back in (purple power!). You want to fill it up until it's 1/2 an inch below the filler hole (according to Chiltons)


Yes, Wrangler Forums will make you a wizard.

Hope this helps!

You tossed back 5 beers in the time it took to take off the rear diff cover....?

Very impressive

My kidneys and liver thank you. That thing was a pain in the butt though. I don't think the diff has ever been flushed before.

That is the mythical wonderful beast they call the Dana 35. You can spot her majestic rubber fill plug.

I usually take a BF(rubber)H to the housing to get it open. How did you paint it and keep the white lettering? That looks great!

I primed it, then painted it black with dark black primer. The lady came out with a steady hand and some model airplane paint (i'm still a 14 year old kid at heart) then everything was dried with a 1500watt electronics heating death gun. Clear coat was then added...and death star'd also.

Me blowing the Dana 35 up 4 times (once on 31 inch A/T's with a 4 banger) tells me different.
