Best gear oil?

eng53ine · Feb 1, 2017

What's the oil/ lube for the front end that you can get at a parts store? What kind of goo would be best to seal it back up, without having to order and wait for anything?
Thanks

I think the front calls for 80w90 where the rear calls for 75w140? Any good 80w90 will be good for the front. And I only use ford gray diesel sealant on everything.

Right stuff 1min sealant works good as well. Best part is l,you can use the truck instantly. No leaks from my rear end using the stuff, I only have 2,000miles since I changed the oil though.

Only 80w90 zone had was valvoline, I got the synthetic is it any good? Got the one minute sealer to try.

That's the same as I put in my dads truck. It's good stuff, just clean the surface real good and you won't have any trouble with that sealant.

Good deal I've never really used valvoline so I wasn't sure. Thanks for the reply

I think i put it in my obs and work truck as well with good luck. Since I've swapped everything else over I'll probably just buy gallons of LE from here on to keep everything the same.

Use Emory cloth to clean the sealing surface and plenty brake clean. Number one reason they leak is the surface wasn't clesn
