Subject: E30 Steering Column Rattle
I had a similar problem with my '91 318is. In my car there is a
splined shaft (Male portion) protruding through the fire wall to the
interior of the car. (You will have to remove one or two trim panels
on the driver's side to see this. Requires normal sockets or phillips
screw drivers) This splined shaft fits into a mating hollow shaft
which is connected to the steering wheel. At the mating area, the
hollow shaft is split and tapered for about 1/2" then threaded for
about an inch above the tapered section. A cone shaped nut is
screwed on over the two shafts. Tightening the nut causes the
tapered section of the hollow shaft to press against the splined shaft,
prevening the joint from bending. When the nut gets loose, the joint
can move from side to side, causing a rattle over bumpy roads.
Solution: get a very large open end wrench (about 25mm) and tighten
the nut as much as you can. I recommend greasing the spline a little
first. This mechanism allows the steering column to compress in an
accident, so you may want to be a little wary of OVER tightening, but
it took care of my problem.
Good luck,
Robert
