Differential Fluid Change

Forgive me if this has been posted but is there a write up on changing differential fluid in a 4x4 Liberty. I looked but never found one. If not, then if someone can tell me how (I'm sure I can do it with no problem but I don't want to miss a step and damage something) I will do a write up with pics.

The front, you simply drain the bottom but unscrewing the drain plug, put the drain plug back in, then fill through fill hole at the top. The back needs the cover removed, scraped with a gasket scraper to clean off RTV sealant, scrape and clean Differential, Apply more Sealant and put the cover back on the fill it through fill plug

Or better yet, get the Chrysler gasket from Lubelocker. No need to ever mess with RTV again. Just an initial scraping off of the old junk, reinstall cover with the lubelocker gasket, no sealant required. I have even reused my lubelocker gasket a couple of times. Best thing going. You would need the Chrysler 8.25 gasket they have listed right on the home page of the website www.lubelocker.com

Lubelocker gasket 8.25, is what I would like to find up here in Vancouver Canada. Even phoned a 4x4 shop in Bellingham Washington and not to be had. I guess I have to try to get one out of company directly.
Anyone knows who else stocks them on the west coast? Their dealer list is pathetic and many links dont work, no contact tel for lublocker only submit a question.

He's in Canada.

But, LibertyTC, you surely have Fel Pro distributors in Canada, don't you?
Call them armed with the part number that Scott just gave you.

The FelPro gasket worked fine for me. I just rub a thin layer of grease on all cork gaskets prior to installation, and I have never had any problems. Hope this helps!

Thanks Scottunangst,brucebotti, and of course TBJ for your replies!
Fel Pro is no problem up here, which also makes probably a hard Poly Urethane gasket as well, as I use those on valve covers on sedan. Cork ya that is an option, but I really want to try one of the lube lockers. My plan is that come winter I would like to pull the cover for the colder months Nov-March and have the lighter synthetic in. Then after March put in the heavier lube as I will pull occasionally trailer the boat. Using the Lublocker that is re-useable gives me a quick and easy test of the two different oils. I know the lubelocker is over $20, but I would really like to find one. I currently have an email into lubelocker and am waiting for a response. If like last time they refer me to the Bremerton 4x4 shop I will have to contact them again saying been there done that, they want nothing to do with gettin me a couple of your Lubelocker gaskets, and they don't stock them, so who does there Lubelocker or are you just hoping for new retailers to sell your products?, Maybe they just cater to the racings pros, but since they have no retail in Canada they should sell direct online. Even Mopac here which is high end and racing products never heard of them, I guess no one wants them.
The other solution for me then is to find a new diff cover, that has both a fill and drain plug, or get info on installing a drain plug into the stock diff cover.

Just ordered a LubeLocker to go with my new Riddler. Was reading a review on another forum, cant remember the name of the forum, maybe i LOST my memory, anyways the Lube Locker requires bolts torqued to 35 lb ft but the differential is only 30 according to Chrysler. In addition to the bolts are actually Grade 5 which cant be torqued much past 13 lb ft otherwise they can snap in the differential. The guy on the forum obtained Grade 8 Bolts and torqued them to 25 lb fts and hasnt had any leaks. I will do the same.

The Rear Axle is the Chrysler 8.25 which is the same in both Jeeps. No online sites will ship to B.C?
