Diff fluid change

I am gonna change the fluid out of my rear diff, and I was wondering if there is a gasket for the diff? As far as I know there you make a gasket out of rtv. If anybody know's otherwise please let me know, thanks ahead of time for the help.

01 2500, quad cab, 2wd, auto, 132k, turbo rebuilt good as new by htt , and 0216 code for 1 1/2 years now. Airdog 100 fuel system after 3 stock lift pumps.

no gasket just rtv. I get the permatex small tube that goes in the caulking gun and it works great.

When I use the RTV I use brake cleaner fluid after I have cleaned the gasket surface. I let the RTV set up like they say I think it is 10 min then torque them down.

He might not need it, if the clutches are worn out enough. That additive just makes the clutches slip easier. If he does the fluid change and doesn't notice any chatter than you are better off leaving it out.

Ya alot of people love to gob RTV on things. I just spread it evenly with my finger, it makes your fingers a mess, but helps insure you don't end up with big globs of RTV in your oil.

Well he don't have that much more miles than me and I put the lucas stuff in. Said it didn't need any addatives and a week later I started getting a chatter. I went to carquest and got the addative and the noise was gone. There is a reason your suppose to use it.

I agree RTV has given me fits so if I can I buy a gasket. I think RTV requires a very clean surface and for the cure time to be just right, and if you don't clean out the rear end super good it will run down the sealing surface and cause a leak.

Yes I know, but some people think it's always needed and it actually helps the aids in traction.
