leaky rear end

ok, get your heads out of the gutter :gap:

so, / I recently put on a spectre chrome diff cover on my 9.75"

I have found it to be leaking. I used the paper gasket that came with it, and torqued the bolts to 30 ft/lbs

Going to try and just tighten them up with a ratchet, also going to see if I have an axle breather that may be plugged?

If that doesn't work, should I just redo it with RTV? if so, what color is the best?

A friend of mine, actually said he hates those chrome covers because they warp and leak, has anyone here had that issue with them?

I used the grey RTV and it worked good.

I used the grey RTV when I swapped the fluid on my '00 Dakota a couple years ago. Dry as a bone.

If you aren't sure how to make a gasket, go on YouTube and watch a couple videos from mechanics or the manufacturer.

Yep, needed to use the RVT... They came from the factory without a gasket.. Just the RVT.

Didn't even know they made a gasket for the 9.75" ??

Chrome cover? Why?

Holds more heat, will just rust anyway...

Good luck!

so...... looking @ tearing this apart again.....

might as well spend the couple hundred bucks on an aluminum, higher capacity cover, with a drain plug, and a fill plug, and a sight glass. looking @ the AFE, how is it? anyone using it?

Does the axle have a vent port?

The brake line junction on top of the axle is also the vent port, it should have a hose coming off the top.
