Now I'm thinking I need to swap the diff from the Cougar into the 'Bird. I looked at the manual I have for the 93-94 but it seems very difficult, in addition to being different than the 91. I need some help on this. Suggestions, tips, anything. Sean "Now the proud owner of a daily driver" Weijand Budget Blue '89 XR7

Next would be to use a pry Bar of some sort and see if you can get the diff to move.... Click Here "Turning seems to be a lost form."

When I was turning the half shafts by hand they didn't sound all that smooth. Sean "Now the proud owner of a daily driver" Weijand Budget Blue '89 XR7

I'm not sure what your manual says but I will run you down how I did it. - pull the passenger side tire and brake assembly off (caliper and bracket 2 bolts) - pull the spindle off (3 bolts) - I popped the axle out of the diff with a large screwdriver. - Disconnect the abs sensors on both sides of the diff, unbolt drive shaft and slide towards trans. - unbolt diff, jack underneath, you can slide the diff off the other axle and out of the car with very little difficulty. - Install is exact opposite, it took a little time for me to get the new diff on the axle and in the correct position, a 2nd set of hands would be very helpful. Make sure the diff doesn't fall on you, mine did and it hurts , their heavy. Give me a call if you have any problems. -Andrew Last Edited By: Andrew 88 05/27/2008 09:56 PM. Edited 1 times.

The bushings are shot. I will be changing them out this weekend. Thanks Kevin. I will be pulling the diff out of the Cougar thanks to Andrew's advice, hopefully sometime next week.

I'm debating about getting a set from SCP (and maybe a few other things For the Bird) Also doesn't matter which side you start with since you have no exhaust in the car now right?? and RE&RE of the differential is the same for 89-97 cars.. Only Difference would BE ABS and Non ABS, Disk or drum.. Either way, it's not THAT hard of a thing to do.. And i would just Pull both Uprights, and axles just for ht e easy of Removal.. least then you can just lower the Differential.. "Turning seems to be a lost form."

And since the diff is already unbolted I ust have to pop them off and slip them onto the T'bird. I'm hoping I can lower the diff enough to get them on without dealing with the exhaust. I looked at the ones on SCP and I think I'll buy a set but I will have to wait for a month. Sean "Now the proud owner of a daily driver" Weijand Budget Blue '89 XR7

You can remove the bushings without removing the diff.. a jack under the diff (DUH!) unbolt the front two bolts.. lower the jack abit, push the bolt UP and the bushings SHOULD come out I think i had a Bitch of a time Removing them from my '91 (XR7) atleast one of them.. Still wish i had them.. since they were good "Turning seems to be a lost form." "you shouldn't drive faster than your guardian angel can fly"
