Wasn't aware a Merc 190 had an idler arm. However, clunky steering and wander. Observation of the idler arm will show excessive lateral movement
Tires out of balance, Bad tie-rod ends. Steering stablelizer shock, Bent wheel, Belt broken in the tire. Bad idler arm. I would have the front tires balanced first.
That depends on when it shakes. Low speed, it could be a bad tire, bent wheel... High speed, it could be a bad tire, bent wheel, out of balance wheel, worn ball joints, worn tie rod ends, worn idler arm...
it could be the idler arm. i have a 96 s10 blazer and the idler arm is bad everytime i parallel park and cut the wheel all the way in either direction my front end pops
A bad lower control arm can cause the car to shake, wander, or be hard to steer. If the arm breaks or comes loose, then you will lose control and not be able to steer the vehicle.
no, bad alignments come from potholes or front suspension parts needing replaced like your tie rod ends or idler arm.
Bad tires and bad alignment can cause the car to shake at certain speeds.
Bad engine cushions can make the engine shake. bad spark plugs cause malfunction as the car starts running.
The hardest part of changing an idler arm is getting the linkage separated. To do that you will need a ball joint fork and a big hammer. The end of the idler arm has a tapered shaft that is difficult to pull out. Remove the cotter pin, remove the nut, then start pounding the ball joint fork into the area between the idler arm and the tie rod with your big hammer. The tapered shaft is usually so tight that it takes quite a bit of effort to pull it all loose, but it will eventually come out. After you have pounded quite a while the thing will eventually come out, THEN disconnect the rest of the idler arm from he frame of the vehicle. It can be one of the more frustrating jobs related to working on automobiles. This particular vehicle has TWO idler arms, and they usually go bad at the same time. You will probably want to get the alignment checked after replacing the idlers.
You need to replace your tie rods, pitman arm and idler arm. I had the same problem and it went away. Cost me about $120.00
The car can wander (moving from side to side without turning the steering wheel.) There can be play in the steering wheel as well.
Most certainly.
