Hey fellas,

I'm doing the front and rear differential fluid tomorrow, and I have two questions. I do not have a gasket for the front. Is it true that some RTV sealant is all I need for a good seal, as long as I clean the surfaces and torque properly? That leads me into my second question. What are the torque specs for the front and rear bolts? Also, if anyone could provide a link to a torque wrench that is good for this job, that'd be awesome. I need to pick one up.

I picked up a manual (not digital) torque wrench at Sears for around $30. It's worked well for me for 6 months, and I can replace it if it breaks.

Black Rtv is rated for oil and is fine. I've got a torque wrench and a Haynes service manual you can borrow. I don't live too far from you. Do you need ramps? Are you doing it in your garage?

I'd love to borrow a torque wrench, thanks fellas. I'm planning on doing this tomorrow evening in my garage, sometime after 5:30pm. Any chance you guys would like some free beer as you walk me through it the first time? The Mrs would be happy to cook you up something delicious as well. It would be cool to be shown any small tips / tricks to doing this. I may need ramps now that I think of it. My jack is a low-profile jack to get under my SRT. The Axles need to be suspended in air in order to get to all the bolts on the diff covers, correct?

no... i did mine without a jack or ramps. a few tips

leave the top bolt in (but loosen it up, that way, when it drains, the cover wont fall into the drip pan, and when it is done, then take the top bolt out)

make sure you use your RTV (if you arent using a gasket) on the inside of the bolts, as in when your applying it, think of it as a wall. if you put a wall in front of the hole, your good, but if you put the wall behind the hole, oil will seep out from the bolts.

let the RTV cure for about 15 - 20 minutes (it expands). if you try to fill it up right after, the diff fluid will leak right out.

i cant think of anything else... but if i think of something new, ill let you know.

what fluid you plan on using?

welp, valve cover gasket changed with only minor casualties. Then I found out it wasn't the drip that had been making spots all over works parking lot. Stupid heater control valve was leaking and making the wet spots.

It needed changed anyway.

Thanks very much for the offer. I'm working overtime tonight until 9:30pm I doubt you'll feel any more like doing it at that point than I will lol.

@Jakbob - Got it, I will make sure not to put the RTV on the outside of the bolts. Makes sense.

Atleast it want like me... I towed a haul trailer to work (a 6x12 enclosed) and then when I came out for lunch, there was a huge puddle of fluid under my driver front seat. Turns out the trailer was a little heavy for the jeep, causing excessive blow-by because of my worn rings, and was blowing so much oil into the airbox, it was leaking out the bottom. I thought it was PS fluid. Also, are you going to tune your antenna? I got an SWR meter and extra cable.

@Passt - I just didn't think I explained it enough :/
