So there is transfer fluid spewing from the top of the 4x4 transfer box, which has knocked out the PAS. At least that's what I am thinking so far. Have had er differing opinions.
Anybody got any experience with these things ? The fluid seems to be coming from a breather pipe on the top of the transfer box, and have filled it with 2 litres of fluid twice which was just spat back out.
Somebody offered to bypass something to get the power assisted streering on, but need to be sure b4 I right off the 4wd system. But I need to be sure....
Perhaps I could rip off the front drive shafts, weld some cogs together in the transfer box and do a rear wheel drive conversion. Who's got experience in that ??!
What you are experiencing is pressure seal failure im afraid. If you want to keep driveing the car your best bet is to pull fuse 19, then top up the power steering fluid. There is no easy fix on this. You need a new transfer box.
Its possible you have damaged the internals if you have been driveing it in this condition. As for welding it up. Erm no - doesnt quite work like that! Have a word with richard king. firstname.lastname@example.org
As Andy says you have a classic 'pressure plate seal' failure. The seal is what keeps the steering oil out of the transfer box under normal conditions. You will need to explore the reason for failure. It may have just been tired or the Accumulator bulb has gone passed its service life and failed.
All the information about your transfer box can be found in the Workshop Manual
Before you panic you wont need a whole new t/x box. Depending on the damage it may just be a new seal thats needed.
What you want to do is pull fuse 19, drain the centre section of all PAS fluid then refill (thru the breather pipe) with the proper gear oil (Vauxhall Part No. - 90443530) just to keep the gears in good condition.
The causeof the problem is normally uneven tyre wear. This constant difference of tyre rotation starts to build up a LOT of heat which causes the seal to perish.
It can also mean that the pressure plate is exerting more pressure on the clutch rings to keep the drive connected which eventually pushes the seal thru.
