    YouŽll have to take out 2 drain plugs. I think Alfajack posted some pictures of them.

    The top two pages are from the red owners manual which should come with the car, I think one book covers all 92-95 155s so you may be able to get hold of one fairly easily

    I plan to change the oil in the rear diff, because it is not known when was last changed (if it is changed at all). I will use Motul Gear 300 -> link. Does someone use this oil for rear diff and/or gearbox? What oil did you use?

    You probably changed all the oils long time ago ...I've used Gear 300 too for my rear diff 3 years ago when it was rebuilt/refurbished. My gearbox/central diff on the other hand was dis- and reassembled 2 weeks ago and I've bought Motul HD 80w90 for that.
