I received my new Mag-Hytec cover today. What a trick piece! It's very well thought out. Excellent fit and finish. It comes with all stainless hardware. The drain plug, dipstick and fluid level reference plugs are all stainless and have O-ring seals. The cover also is sealed by an O-ring that is seated in a machined groove in the gasket surface. The only thing you would have to use any kind of sealant on is the threaded port for the temperature sending unit, if you choose to run one. It comes with a plug in place from the manufacturer. No gaskets, no silicon. The drain plug and dipstick both have magnets embedded in them to catch and hold all the nasties floating around in there. They even give you the Allen wrenches to install it! Plus, it looks cool too! I'm impressed. And I'm not an easy one to please. Of course I filled it with fresh LE 607 and a bottle of friction modifier. I just hate they don't have a tranny pan for the 4R70W yet. You can bet, as soon as they do I'll have one on the way!
Oh yeah, www.Mag-Hytec.com

98FWORD,
I agree, the Mag-Hytec parts are 1st Class! Unfortunately, Roy is just starting development of the 9.75" covers. They pretty much all the features I would want in an ideal world for a diff cover.
Why not go ahead an install the temp sensor? Also, if you haven't already, you might consider adding a trans temp gauge. I did the trans temp first (Autometer Electric), and am in the process of adding the temp sensor to the diff. The etra temp sensor, at the local speed shop, cost me $10.
I will be switching between the 2 sensors to one gauge. If you are interested, I'll foreward you the wiring diagram I used: Of course, with the caveat that you install at your own risk, since I don't know your technical level. Anyway, I'm getting ahead of myself.

F150Tony,

I have considered temp sensors and guages for both the tranny and differential. I used to tow a boat that weighed about 2000 pounds. I've since sold that money toilet. I hardly ever pull much of a load with it now. I do know that since I put the Mag-Hytec cover on I am now able to make a long run and afterwards put my hand on it and hold it there. Where before, it would get uncomfortable to keep my hand on the cover much quicker. There is a definite difference in the operating temperature with the Mag-Hytec cover on there. I'm not worried about an overheating problem in my differential now. One of the bearing races that came out of my rear differential when I had the gears changed had a chunk missing out of the bearing surface. I don't know what the cause of that failure was for sure. It looked like it might have been a peice of trash or the race itself may have been defective. One thing is for certain though, there were no signs of excessive heat on the bearings or ring and pinion. And that's with the lube that it came with from the factory, the stock cover and 19K miles. Being that there wasn't any overheating problems with that setup, I don't worry a bit with the superior lubricating qualities of the LE 607 and the addition of the Mag-Hytec cover with larger fluid capacity, better cooling and magnets to keep the nasties from causing problems.

I don't have a sway bar on my truck but, they give a word of caution in the instructions addressing this issue.

"There may be clearance problems between your Mag-Hytec cover and other vehicle systems (specifically some sway bars). It may be necessary to install spacers or shims to lower the sway bar".

The sway bar would have to be pretty close to the stock cover for it to cause a clearance problem with the Mag-Hytec cover. It does protrude a little farther than the stock one, but not that much. As I said earlier, I don't have one on my truck. So, I couldn't tell you for sure.

OK, the Mag-Hytec rear diff cover seems like the way to go. OK, here's a question:

Will I still be able to mount a Hellwig rear stabilizer bar with the new larger Mag-Hytecdifferential cover? Anybody have these two (Hellwig + Mag-Hytec) together?

The rear anti-sway bar goes in front of the axle; shouldn't be a problem. This is not the case on the OEM rear anti-sway bar on the Expedition (it mounts behind).

Thanks,

I have a call into Hellwig as well to verify.

Thanks again.
