Well the diff has been removed and rebuilt but those shafts from the axle still need to get their new bearings fitted so that they can be refitted too, before this Jeep is going anywhere!
Here is one of the two shafts removed from either side of the rear axle.
To remove the bearing first we had to remove the retaining ring, and so a small pilot hole was drilled.
The hole in the retaining ring was drilled larger...
...this made it very easy to split the ring open with a small metal chisel.
After a few hits the ring opened up and was removed.
The bearing race was also opened up with the chisel, so that the rollers and cage would come off.
The inner part of the bearing was going to be a bit trickier...
...for this we got out a cutting tool, which soon made light work of it!
We managed to get the bearing off without causing any damage.
The metal mounting bracket/plate was also removed just to flatten it back a little. Don't forget to refit it before replacing the bearing on the shafts if you remove yours.
The flat mounting bracket and the outer rubber seal for the new bearing are put on the shaft. Grease is smeared around the seal.
The new roller bearing and retaining ring are lowered into place.
Using a jack on this pipe bending device would allow us to fit the bearing.
With the bearing release tool placed above the bearing on the shaft, we would be able to clamp the whole thing together, thus forcing the bearing down the shaft.
The bearing has been pressed on!
Next we did the same with the retaining ring.
Jacking up the shaft, again forcing the bearing retainer down the length of the shaft.
That was easy enough.
Now by putting some insulation tape around the seal and then pulling the seal up to the bearing, the bearing was very easily greased all the way through.
Then just do the same with the second half shaft and refit both shafts back in the rear axle.
Ater this refit the back brake shoes and drums and then the wheels.
Don't forget to reconnect the rear drive shaft too!
To complete the whole process the last thing left to do was to add the new axle oil.
After adding most of the oil, the Jeep was moved down the drive and then it was backed up onto the ramps as this gave us an incline that then allowed the rest of the total of 1.9 litres of axle oil that needed to be added to be poured in.
The axle now runs far quieter than it was doing before.
Oh, and don't forget to return any tools you have borrowed off other people!...
...you never know when you might want to borrow some more!
