to check the rear you need to take the wheel and brake pads off.
so these needle rollers where do they belong are they going to be ratling around my gearbox now or not
wash all the crap out of what and what crap i assume you mean mud etc but i never left the tarmac so i doubt there is any
Needles are in the universal joint bearings the three bearings on the end of that section of shaft , they look ok but without having hands on its hard to tell
The crap is the grease on the shaft end and in the boot degrease and replace with fresh cv grease and new boot rubber
The rubber boot maybe split so will need replaced
If you take of the rubber that is still attached to the car it will reveal the cup the end it goes into. make sure the spring is still in there its pretty simple you need to remove the end of the shaft that is attached to the hub at the wheel end dismantle it and refit a new boot ( look for the faq)
Or buy a second hand shaft from ??? And refit
Your gearbox should be fine is the seal leaking ???
If it is buy a new gearbox seal
Try and get some pics of the steering rack and tie rods id replace the tie rod end as a matter of course there around 15bucks for a good one lemforder are good or febi
Switched my hub bearing changed the tie rod end changed the cv boots and the shocks top mounts changed the springs n put b8s etc today its fairly simple once you get going i dont have a garage all is done on the drive so have become fairly swift in operation
But can be easily done in a couple of days if you new to these jobs
Bonus if you have a garage
