850 Steering Issues 850 1996

In late July, upon getting the 850 back from their mechanic (who was supposed to do a timing belt job, but literally broke the engine, and installed a rebuilt engine at my parents' cost) my parents immediately noticed that the steering was very hard-as if the power assist wasn't working, especially at 1-3 mph.

After resolving all the various issues which resulted from my parents' mechanic installing the engine improperly (and that is a very kind way of putting it), my friend (who is a BMW mechanic), yesterday, tackled the steering issue. After taking the 850 for a test drive, he admitted that the steering did seem hard. He looked at the fluid level, and it seemed fine. No noises (which if there were, one would imagine that the fluid was low or that the pump was failing) were to be heard. He looked at the rack, and the inner/outer tie-rods, and they were fine.

A little less than four years ago, the original steering rack was seeping fluid, so my parents had it replaced with a rebuilt rack at another mechanic's shop. The tie-rods are about two years old, and are TRW brand parts. I honestly don't believe that the steering pump, which if memory serves me correctly is attached to the reservoir, has ever been replaced. When I return to the States, at the end of October, I am going to put back on the stock Volvo wheels, which should make something of a difference seeing as the 215/45/17 tires should be causing a little extra drag-but, something of which my parents had never complained previously.

It is a little difficult for me, being almost 10,000 kilometers away from the car, to do too much, but I figured I could at least seek input so that when I am back in the States I can continue to address the problem.

Thanks, and I hope that everyone has a most splendid "Tag der Deutschen Einheit." :D

Have you lubed the steering shaft u-joints? On both my 240 and 850 the lower joint corroded causing stiff and difficult steering.

I sprayed WD-40 into the joint as I worked the steering from lock to lock for a few minutes. Voila! You might need to do this a few times for it to work and will probably need to repeat every so often...

I'd have to believe that when the mechanic switched engine he would keep the car's power steering pump as opposed to one being on the rebuilt engine, though I've been wrong many times before.

If your mechanic friend is available to help (or your parents have some mechanical aptitude) have them flush the steering. Use synthetic ATF.

Here's a pdf showing how to check pump pressure as well as balance (and torque to turn the wheel so much)

The apparatus can be built relatively easily and tested to determine if the steering gear or pump is malfunctioning.

My initial thought is the fluid is crap followed by the pump.

Thank you, tmannian and jwalker! :D

When I get back to the States, at the end of October, I will flush the steering fluid-as well as lubing the steering shaft u-joint.

I greatly appreciate the input, and I hope that everyone has a most splendid Monday :D

Cheers!
