i am about to order a new rear diff cover for my 00 f150
it is 12 bolt, but how do i find out what size, and is it better to get a larger capacity one or it doesnt matter? and is 4wheelparts a good place to buy one from?
thanks

 

You should have a tag on the rear end cover now under one of the cover bolts. It will either be a 8.8 or a 9.75. Look for one of those two covers and that's what you'll need. Larger capacity is nice and helps the fluid run a little cooler. Beneficial if you're towing. Not much other benefit otherwise. What kind of cover is it?? I ask because you don't want chrome. Chrome is the worst dissipator of heat you can get on a component. It actually holds heat in. Although the effects are minimal at best, still bugs the crap out of me Mag-Hytec is the diff cover of choise. Go check that one out. Kinda pricey but worth it.

 

so are you saying i have to take the cover off to find out what i have?
thanks

 

On the outside of the cover, a tag will be bolted on with the cover. You will be able to read it without opening the case.

 

ok thanks
and holy crap the mag hytec covers are 250!!!

 

You get what you pay for!! ANY other cover will cheap in comparison.

 

They are actually cheaper than I thought....I'm ordering one within the next couple of days

 

X2..

 

FYI, I just ordered a Mag Hytec diff cover for $238 on ebay.

 

alright i found the size its 9.75
i am going to dish out the cash to get the mag-hytec, so its not hurting anything to have the more capacity one, even though i dont tow or anything?
thanks for all the help

 

I bought mine 90% for looks

 

I've had a Mag on my truck for a few years now. My only complaint is that the spare tire no longer fits underneath the tuck. I called and spoke to someone at Mag about this and was told this was the first time they'd ever heard of it. That's hard for me to believe, but it's a nice cover nonetheless.

pm me before ya'll buy one. period.

 

eh i decided to just go with a factory replacement for only 40 bucks. i dont tow or anything so it really didnt matter, need to save the money, christmas is coming!

 

Crash, I don't have PM privliges yet, can you PM me (will I be able to respond?) or email me? I was considering a Mag-Hytec tranny pan. I'm getting ready to flush and swap to synthetics.
