I have a 1992 Subaru Justy, 5 speed, 4WD that has lost it's front driving wheels but still has the rear wheels driving it in 4WD.
When my rear wheels spin in the snow, I can hear a grinding or rattling coming from underneath.
All joints and external parts look good, so I'm
sure the problem is internal.
I am told that there may be an access plate to get at what might be the problem, though I can't see one. I'm told that it could just be a pin fallen out of a gear and thus the gear has dropped. Does any of this make sense and if not what do you recommend I do to get my front wheels driving again?
And if I should leave it as is, is there a danger of the whole drive train seizing up and losing my rear wheels as well?
If the front wheel drive is missing, something has gone wrong with the transfer gears and if you continue to use it, you risk losing the rear wheels as well. The only way to go about is to disassemble to check/repair the fault.
