yep it's amazing what you find on a used car once the engine is out!
I had half of my hub bolts stripped and almost falling out!!!! Driving around like that for 2 years!!
(Hubs needed taking to a workshop to have to be re-threaded of course and they are no ordinary bolts)
Also a driveshaft allen bolt head split in pieces!!!
Overhauling a powersteering rack is not a job for the feint hearted, if you have to take it out, may as well get it looked at, seals ect ect.
To get the boots off you have to undo union banjo's which leak afterwards, normally a specialists job. Not sure if it can be done in-situ, doubt it, I just swapped mine for a non PS rack lol
What you can do is get new boots, cut them along a join, and using glue and rubber, glue it together from the inside.
Although there are boots that are specially designed to be superglued on, I couldnt stand the thought of using glue either.
On my 33 I had the complete steering rack rebuilt because it was also leaking.
It requires special tools and a rebuild kit which adds to the costs.
This rebuild though shouldnt be done by someone who hasnt done it before.
A couple of years ago when I had to change a mates steering rack boots to pass through MOT, we had to deal with this issue.
At the end of the day, he paid 100 Euro for the boots and we took off the rack ourselves, took it to a specialist and he charged us 50 euro just to replace them - which is a very good price.
however he was extremely careful, not to brake any seals while replacing them so that the rack wouldnt start leaking afterwards.
The boots needed to be streched a bit to go through, but job done.
I would suggest you ask a specialist how much he would want to change the boots if you took him the rack and the boots to begin with.
When I did that boot change I was trying to show that it could be done without removing the rack leading to leaks etc. Not everyone has money these days and this aproach could be the difference between a 33 on the road or one sat in the scrapyard. It cost 6 pounds to do and 3 years on is still perfectly sound doing the same job as one that would cost 200 plus to put on......keeping dust off a hydraulic shaft.
