I've spent the last three days underneath the 2001 '100-Series'.
I had a leaking N/S rear axle oil seal so pulled the half shaft. As I suspected, it was my fault

.
I removed the diff and replaced the back brake dust shields last year. This meant pulling the spacers/ABS rings/wheel bearings off the half shafts in order to replace the shields (which are also the back brake mountings so are heavy-duty).
When putting it all together I didn't get the ABS Ring and spacer (that runs in the oil seal) in quite the right place - it was 4mm out - meaning that the oil seal was on the edge of the spacer and leaked.
A new ABS Ring and Spacer and some more careful measurement has hopefully sorted that little whoopsie.
While it was in the garage and up on stands (while it was hailing outside, this really is the Frozen North) I set about changing the rear ARB Bushes and Drop Links.
Now, for all you guys down South this will be less than an hours work. Unfortunately 14 years of road salt meant that It took me an hour per bolt to remove the old bits.
I had to carefully re-position ABS cables, handbrake cable and so on, wire brush the rust as best I could then use a propane torch CAREFULLY on each bolt.
After 15 mins or so I was able to get some movement on the bolts with a six-point socket on an 18" power bar. It was then a matter of carefully working them back and forth until they were out. The bolts are toast but the threads in the axle & chassis survived so no Helicoiling or Riv-Nutting this time.
The ARB was cleaned back to bare metal and given two coats of Smoothrite before fitting the orange bushes with stainless bolts and lots of anti-sieze paste.
The brackets that the drop links bolt to were also cleaned back to bare steel and painted.
It looks nice, but it will be rusty again within a month I reckon. It should impress the MOT Tester later this month though.
Horse towing on Monday and then I have to tackle the front ARB bushes and links and fit new front AHC suspension struts

.
It never ends.
Bob.
