I have a 1997 Isuzu Rodeo. The steering wheel shakes when driving
straight. It is worse between 45 and 50 mph but shakes at other speeds
also. It is not as pronounnced if you are steering either left or
right. I had the wheels balanced and the front end align when I
started noticing it. The alignment and balance had no affect. It has
since gotten worse. Any ideas - ball joints, bushing, rotors?
Any advice appreciated.
Rotate the tires. Could be a bad tire. Out of round, off center tread,
beginning of tread seperation etc. Maybe a bent rim? Have the tires
balanced on the vehicle. Only a few places can do this though.
Have your front end and power steering checked. The front ends on these
things are pretty solid, so it's unlikely a worn ball joint, but it's
possible, and a careless alignment guy can miss it. Sometimes a bad pump
can cause this too.
