Both rear half shafts were in a pretty poor condition. No way it would have passed an MOT. Both UJs where shot and both trunnion joints seized
Removal of the UJs was straight forward. I just needed a big enough hammer.
The trunnion bolts were a different story. Soaking both ends of the bolt in WD40 and then applying my impact driver had no effect. Trying to hammer the bolt back through the trunnion housing was also futile, regardless of the size of the hammer used. The only other way was to cut them off with a hacksaw. It’s a delicate process. I needed to position the hacksaw parallel with the trunnion and the vertical link and cut through the old nylon bush to the bolt without damaging the trunnion face of vertical link.
As the wheel bearings seemed fine, I stopped disassembly there, before wire brushing and re-paining all the components. The new UJs slipped in without any problems at all.
The trunnion bushes required a little concentration. I applied plenty of normal grease to the inside bore oof the trunnion and the inside of the nylon bush before seating them in place. The dust caps and rubber seals also had a generous coating of normal grease. The new bolt I covered in copper grease in the hope of preventing it from seizing up in future. Positioning the vertical link over the trunnion with the dust caps in place is tricky as the vertical link will tend to push the duct caps out of position. To prevent this I opened up the vertical link slightly with a clamp. Once in place I tighten these a tight as I could whilst still allowing movement. I will leave them to settle and complete with the torque wrench before they go back on.
As I had the rear hub is pieces I treated the brakes to new slave cylinders, dust caps and clips
And there we have it. 2 refurbished half shafts
