ThankYou for pointing that out glc. So I should be alright with a 4.10 in the front? I also found a rebuild kit from summit for an 8.8 but it's for the mustang. Do they have the same pumpkin? The picture looks like it would fit but that means nothing...

I already have most of the bearings so I'll prolly just buy what I need and a new crush sleeve. I just have to count the splines and get the right one I believe.

 

The front in your 98 is a Ford 8.8 with reverse cut gears.

 

I thought it was but I didn't know that the gears were reverse cut. I'll have to make sure to check that when I order. Anything else I should know? I appreciate he help thanks

 

Above pictures are of the "tool" I made to allow me to compress the springs of the limited slip clutches I was trying to put the pinion gears back in at work.

This "tool" was just a 3/8X3/4inc long bolt that I shortened a little more to be 7/8" over all long including the head. I then screwed a 3/8 nut on as far as it would go and then put a 1/4 inch thick washer on the end which when butted up to the nut was just flush with the end of the bolt.

The way this worked was after I installed the side gears with the springs, shims and clutch disks I was able to put the "C" clips in the grooves on the axles by using a pry bar in grooves to compress the springs enough to allow the "C" clips to slip in. While doing the next steps I had the transmission in park to hold the ring gear from moving. Now with both of the axles clipped in to the side gears I was able to wedge the axles apart enough to get the bolt and washer tool between the inner ends of the axles. It was then a simple matter of backing of the nut while holding the bolt head till the springs were compressed. At first I had a little too much pressure on the axles and it was very hard to turn one even with a good pry bar. I just backed off the tool a little and was able to turn the left axle with a two foot pry bar with out too much trouble.

I then put the pinion gears with washers in place being sure they were directly opposite each other. While I held them in position I had a trusted helper slowly turn the left axle and the pinion gears easily slid into position stopping when the were aligned with the holes for the shaft. I then loosened the "tool" and it dropped right out. It was then a simple matter to slide the pinion shaft into place and install the lock bolt.

It took way less time to do this than it did to write it out or I'm sure for you to read it. Looks like the pictures are going to show. I wish I had thought to take a picture of the "tool" while it was in place in the diff. but I'm sure you can understand how it works.

 

You may want to check with a mechanic before you do that kind of hting to your car.
