Differential leak...

[edbo]

My pinion seal was leaking and had it changed also. Since it's going to cost 100.00 anyway, why not have the gears changed out while their in there?

Had the same problem and was taken care of with a gear change. If you're even remotely considering a gear change, I'd go ahead and get it done and save the extra 100 bucks by just getting the repair done. Just make sure you can get a decent deal on getting the gears done. Mine cost 300 for installation, 150 for the gears and 80 bucks for the rebuild kit. Kind of costly compared to the 100 buck repair but the results are the most awesome of nearly any modification you can get.

i have a question here, the tag on the diff calls for 75-140 synthetic, so i bought valvoline synpower. on the bottle it says limites slip after the weight. and on the back it says its made especially for limited slip differentials. so i bought friction modifier from ford and used it too just to be safe. but do you have to use friction modifier with synth. fluid? i just re-sealed my cover because it was leaking, just to make sure i got enough permatex on there i put a bead on the inner and outer part of the cover and around all the bolt holes cause thats were it looked like they put it from the factory. is that right, im waiting til tomorrow to drive the car because the permatex says it takes 24 hours to completely cure.

You did the right thing and as long as the clutches aren't popping while turning then your additives are ok. I only run 1 bead of sealer on the cover and let it dry like you and have never had a problem with a leaking cover.

yes you need the friction modifier. you are fine on the sealant but I've never had one leak and always filled within an hour and drive. I use the red NAPA sealant in the bottle though.
