Rear Differential

[Oil Ape]

I'm getting ready to syntheticate my rear differential and was wondering what to use to seal it back up with when I put the cover back on? Thanks... ... ...

Any old RTV rated for relatively low heat should do... . just get all the old RTV off the cover and the differential and it should seal very well.



Razor scrapers work really well for this... . then I use a bit of Scotch-Brite to get off all the little stuff. Pneumatic rotary tools with a wire brush will work well too... .

You already have the Mag-Hytec transmission pan. Now is the time to get your rear covered as well. What do you get for ~235? A drain plug, good looks, dip stick to check the level and a lot of extra oil capacity.

Yea, I'd like to upgrade to the Mag-Hytec rear diff cover but I haven't seen a money tree anywhere around where I live. The question I guess I ought to ask is whether I need to service the rear diff enough to warrant that upgrade? and those of you that are monitoring the rear diff temps, what are you finding?



I'm saving my nickles and dimes and preparing and replacing piece by piece with my next upgrades being a cam plate(any suggestions?) and a DTT transmission upgrade...



Thanks for all the comments.

I'd do governor springs before doing a camplate..... but that's just my opinion. The springs make a HUGE difference in how the truck 'feels' and drives down the road..... the engine no longer feels like it is even working hard at all..... this is from the governor delaying the point at which defueling occurs with the upgraded springs/seats.

Diff temps are not a problem. My Dana 70 never goes over 175 while pulling hard on hot days. I just like to have the gauge to spot a problem. Any warmer than normal trend is going to get my attention. All in all, if you're not pulling heavy, I would stick with stock cover and save the money.

 

[HoleshotHolset]

I agree with Larry... .

If you aren't beating on the thing... there is no need for more capacity or cooling.



The Dana-70/80 are stout pieces and if you treat 'em right... . they'll last.

fluid choice

What fluid are you replacing with? I'm looking at doing my rear as well. 40k miles... it's time

I'm using Amsoil Series 2000 75w-140. Technically that is the weight that my owners manual says to use for towing applications and I've used Amsoil in other vehicles with great results.



I know a lot of other people with Limited Slip diff's that have had all sorts of trouble with a wide variety of lubes. There is also quite a group running Amsoil's 75w-90 weight. Stock diff's come with straight 90wt. Mine doesn't have limited slip so I'm not too worried about it. Just wanted a good lube and Amsoil seemed as good a choice as any.



If you go Amsoil, sign up for the preferred customer online and you get there wholesale price on their stuff. It was cheaper than the local rep.

thanks

That's what I needed to know, thanks ape.



Folks, this is why the TDR forums are great. Information rules.

Bickering and biased statements show poor gene pool characteristics, don't you think?
