d35 LS


a non ls axle

Absolutely no need to let it sit that long. I let mine sit for like 1/2 hour, fill, and drive away.

As long as you created a good even bead of RTV and tightened down the bolts it will be absolutely fine. As said before, RTV cures based on a chemical change. It will still be softish until about 24 hours, but it can be filled and driven right away.

Pardon me for my ignorance, but the only difference I see is that the LS is black and the non LS isn't...

Can you point out the difference for me
Thanks

OOdynamite

Cool thanks

The limited slip carrier looks like a can with a flat end

The open diff has an angled bevel on the end of the can

Open left, LS Right

Ok, I see now, thank you

Don't meant to steal this thread, but can i use blue gasket maker? Same stuff i used for my water pump...

EDIT: On second thought, I'm not stealing it anyways cause the thread is over a year old... haha

Hahaha i'm sure blue will work fine. Most people use black for the diffs. but i don't think you'll have a problem with blue

I've had the black skin and start to harden fast in really hot weather. Shouldn't be a problem on a differential. The blue takes longer.

I've been using the new Permatex "Gear Lube" RTV. Works good. Hard to find though. My alternate is Ultra Gray RTV. I stopped using black RTV a long time ago. It serves no useful purpose.

Howdy Ken. Not to be argumentative, I appreciate and respect your posts. I even check to see what gem you shared sometimes, BUT!

Really? I buy nothing but Black. I even used it to secure the "tire" on my 14 inch Rockwell Delta band-saw last week, as well as on all my auto stuff without a problem..yet...that I'm aware of. (just ripped 20' of 4 inch fir with that saw)

It DOES seem it lacks the integrity of "pure silicone", and I did notice that, is why I bothered to bring it up. Do you find it doesent "stick", or does if somehow "break down"?

I offer the question with the greatest respect. I have seen you know your stuff.

Another option is Ford P/N TA29 (grey). It's awesome stuff for sealing parts with oil exposure.

I've had great results with Permatex's The Right Stuff on diffs.

DFlintstone,

I've always triued to use the recommended fluids, sealants, gasket makers, etc., whenever possible, but as belvedere pointed out the Permatex Right Stuff Grey 85144 seems to be a good choice as an all around gasket maker. If you go to the Permatex web site http://www.permatex.com/products/Aut...ket_makers.htm
and click on the blue text below the Right Stuff tube it will open to the various sizes available. To the right you can click on "TDS" (technical data sheet) pdf file and read about it. I like the fact that with this product you assemble the parts within 5 minutes and torque to recommended specs, which goes along with FSM procedures. And I like the fact you can put the item back into service immediately.

Permatex offers an Automatic Transmission RTV Sealant gasket maker which I've used on my TC with great results. I'm currently working on a 242 and am a little leary of using something else besides the Permatex Automatic Transmission RTV Sealant 81180 because I know it works. I really don't want to be a ginea pig using Right Stuff on this TC because it's a lot easier to redo a differential cover if it doesn't work than to have to remove and rework a TC if it doesn't work.

As for removing old RTV, I use a product called Contractors' Solvent. It melts old RTV. Sometimes it takes awhile to loosen the old RTV but it's worth it. I still have to use a small wire brush to agitate the solvent in some places while its working but it does the bulk of the RTV removal. Minimum scraping involved. Of course final clean up of the flange surfaces is with Acetone.

Thanks for the info on Right Stuff belvedere.

Yes and you can break-up any air bubbles by rubbing your finger around in the RTV after you apply it.
