How much torque do I use to tighten the idler arm
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
no, bad alignments come from potholes or front suspension parts needing replaced like your tie rod ends or idler arm.
No, there is a pitman arm on the steering box and two idler arms on the linkage.
Worn idler arm, worn pitman arm, broken sway bar links,
Center link
Changing an Idler Arm on a '99 Saturn is MIGHTY difficult, especially since they don't have one. The '99 Saturn uses a Rack and Pinion steering system, and as such does not have an idler arm.
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.
Remove the bolts and nuts holding the idler arm to the frame# Raise and safely support the vehicle. # Remove the cotter pin, nut and washer retaining the center link to the idler arm. Discard the cotter pin. # Remove the center link from the idler arm. # Remove the bolts and nuts holding the idler arm to the frame and remove the idler arm. To install: # Install the idler arm to the frame with the bolts and nuts. Tighten to 85-97 ft. lbs. (115-132 Nm). # Place the idler arm and front wheels in the straight-ahead position to maintain steering wheel alignment and prevent bushing damage. # Install the center link nut and washer and tighten to 43-47 ft. lbs. (59-63 Nm). Install a new cotter pin. If, after the nut has been torqued, the nut castellations and stud hole do not align for cotter pin installation, tighten the nut further until the cotter pin can be installed. Never back off the nut.# Lower the vehicle. For more info. and pictures check out Related links below...
This is very easy. Remove the nut securing the arm to the drag ling. Then, use a tie-rod separator to separate the arm from the drag link. Next, remove the two bolts securing the arm to the truck frame. Install in reverse order. Next take the truck to an alignment shop for a wheel alignment. Failure to do soe is likely to result in incorrect toe-in and rapid tire wear.
