fluid change in axles

[fgtex]

Hello All,

Question. I am crazy or are there no drain plugs on the stock 2002 F350 4x4 SRW front and rear axles? Do I have to take the covers off to change the fluid? I see the inspection/fill plug, but not one lower than that. If so, I will have to wait until I can get some new covers.

I am thinking












YEP, pop the covers, that way you get a look inside to.
95% sure

even my 02 dually the cover had to be popped off

You have to remove the covers to get the old oil out unless you get a small pump and suck it out but it is much better to remove the covers. You don't have to replace the covers with new ones just clean them up, run a bead of silicone around them and reinstall.

And enjoy the smell of gear lube!!

And use 75-140 synthetic gear lube in the rear as per your owners manual. A little less than 4 qts.

If you have a limited slip you'll want to add about 6-8 oz of friction modifier. The key with that is to use as little as possible to cease the "chatter" in the rear.

You can use brakleen on the diff cover and use a gasket scraper to get it off the diff cover and pumpkin itself. Try to avoid using Brakleen (while some say its ok) on your internals since it is a lubrication killer and if travels somehow down your axle tubes can deteriorate the wheel bearing grease. There is a blue tube at your local store called PERMAtech, and that is what I used. It is simple, and fun if you ask me. I have yet to do my stroker but I did my Mazda and my friends Jeep, check my profile for pics.

Nice to have another knowledgable member on board. Welcome!

What everybody else said, excpet I want to stress the SPECIAL fluid needed in the rear diff. 75w 140 synthetic. It is EXPENSIVE!!! But without it, you Sterling 10.5" rear end will become road debris.

I honestly don't know much... I only post on projects I have done/researched for whatever reason.

CPS, AxleSeals, HPOP Orings, and other minor things. I've always loved lifted trucks and had some so I know about gear ratio's, and stuff like that. BTW I'm only 19.
