Ok, I doubt anybody is going to answer this one, but I'll give it a shot..
My newish HR31 Passage, fine in most other respects, has got some major ass problems.
Basically there is a very loud clunking from LHS rear wheel. The problem appears more pronounced when you get one back wheel off the ground during a 90deg turn (into a driveway, etc), makes a huge "clunk" and goes into spastic mode. I'll drive along after that, and the whole rear of the car will shudder, feels like the wheel is goinng to fall off (maybe it is.. ).
Other times, it seems to sort itself out and go back to normal, but the rear goes into "minor spastic" mode over a bump, and clunks again for a tiny bit.
The HICAS light will flash on during this, and might stay on once it goes spacco for a bit.
Now... my suspects are either hosed diff (needs major shim? causing the axel to pop out nearly?).. although if it is the diff, then it does seem to turn ok for the most part, and LSD when on full boot when everything is working just like normal? I do have another R200 diff sitting around which I'll try eventually.
The other is the HICAS itself is ****ed, going into a spastic and turning the rear wheels when you're trying to go straight.
So is it more likely to be HICAS or diff related, or something else altogether?
oh - and what does the little house looking thingo on the dash mean?? Mine is always on.
