Working on the 1990 900T


Now for some badly needed catchup on deferred maintenance. I bought this 1990 900 Turbo a couple of years ago as a daily driver. Apart from needing a leaky heater valve replaced, I haven't done much with it. Just a stereo and some tires.

But the vibration in the drive train has finally gotten to the point it's not comfortable to drive at just about any speed. Last weekend I pulled the axles to find the right (turbo) side complete dry on the inner axle tripod bearing (inner C/V joint). The left side was just fine. So now I have to swap the driver cups, get some new parts, and put 'er back together. Oh, and new outer steering rod ends as well. And brake pads and rotors. The fun never ends.

After that and a new headliner, which I intend to document here, should be good to sell to finance another Saab fixer purchase. Or not. Maybe after all the work I'll want to keep it.

was the heater core leak the o-ring seal or the whole core itself?

The valve itself was bad. I replaced the valve with new o-rings, kept the core, and things have been good for a couple of years now.
