Finally got rid of diff whine!! - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

Well after putting up with a whining diff for the past 6 months, last friday, with the help of a mate, we changed the diff. Took out the old 2.77, and replaced it with a 3.08. Ended up only taking us about an hour, and that was with a fair bit of wasted time thrown in talking BS. What a difference it has made. The car now has more pickup (not a huge amout, but I can notice it), and NO DIFF WHINE!!!!! Its like driving a difference car!. Plus as a bonus, the diff I got had really meaty discs, and new PBR pads!!!

Sort of related, I asked my mate (who is a mechanic) how much he would charge to fit a diff (assuming someone supplies their own) and he said, MAXIMUM, $200, including bleeding the brakes.

This evening, im going through all the manual conversion parts with the guy thats helping me fit it, to make sure that we arent missing anything, and then Saturday, 5 speed Fairlane!!!!!

Sounds awesome dude, I wish I knew how to change the diff. The pickup would be slightly better I agree cause 2.77 is so slow of the mark! The diff whine isn't to bad to me especially compared to my mates skyline whine that gives him a headache!

How much did it cost for the 3.08?

3.08's would have to be real cheap!
a wrecker i was at the other day had HEAPS of 3.23 EB diff's.

would a 3.23 diff chew to much juice in an ea 3 speed?

Bass Crazy · 09-30-2003, 20:53

Its not to bad on juice, but sits on 2700-2800rpm @ 100, not ideal for lots of freeway driving.

im thinking i might go a 3.23...

nice work Low NA, keep us posted on the 5spd :)

How does a 3.08 go with a 3 speed? Rev overly high at 100km/h??

Rmyers · 09-30-2003, 22:59

I believe you may haveto get an engineers certificate if your putting a 5 speed in your Fairlane as they never came out in manual. I know it's stoopid but it might save ya the cost of a canary...

Thanks for the replys guys. I havnt had the car on the freeway yet, so Im not sure how high it will rev at 100km/h. As for the engineers cert, I hadnt really thought of that .... DOH!. I rang my insurance, and they were fine with it (RACV), so I assumed it would all be fine. Better give em a call I suppose :)
As for the five speed, went through all the parts last night, which including checking the box out. It has been rebuilt in hte past, and all looks good. Only parts missing now are the flywheel bolts, spigot bearing, and the clutch return spring.

Just an update, rang vic roads, and because its a bolt in conversion, with no modification required, its all good. Just have to call them when its done, so they can change their records.
