    Default Idler Arm replacement

    Anyone here have any experience/advice on swapping out the idler arm on an 05 Sierra? I have a procomp 6" lift on it, which I don't believe affects anything on this part, but thought I'd ask. The two questions I have are 1. What is the absolute best replacement part/manufacturer because I think the Toyo 35's are eating up my steering components pretty fast and I'd like something on there that is an improvement over factory. 2. Do I need a ball stud puller to do this? Most of the idler arms I see on various websites appear to come with a ball stud already in place.
    The front end rattle is back with a vengance and I'm getting the death wobble in the steering wheel now at high speeds (55mph +). I'm almost positive this is the problem, however it could be anything under there- pitman arm, ball ends, who knows. Any input would be greatly appreciated.

    Your 6" lift didnt come with a dropped Idler arm to adjust for the lift.
    Most kits either come with or recommend changing to dropped Idler and Pitman arms to adjust for the lift and keep steering geometry near stock specs.

    idler arms are cake to change a couple bolts and your out talking about 15-20 min to do, you will probably need a pickle fork set to separate the center link and the idler arm, to do the pitman are is a little tricky shoving the gearbox around pitman puller just a pain to do

    Cool idler arm replacement

    If your ProComp kit came with new taller steering knuckles than you dont have to drop the idler or pittman arm. I had to replace my pittman arm at 70,000 mile. I have 05 Silverado with Skyjacker 6inch and 35s. One thing I do is every January I get under my truck and retorque all the lift kit bolts and anything that was loosened to install the lift. We retorqued the bolts when new but its a good idea to retorque once a year also.

    i think the good idler arm maybe $100 and the installation should be about $250. some car dealers charge more to provide better quality service.

    the idler arm is really easy, first take of the nuts that hold the center link to the idler at pitman arms. like Z71 guy said, u will probly need a pickle fork or a puller to get the center link off. after that, take the nut off the idler arm. u will probly need a puller to get it off. when installing the new one, the shaft that u put the idler arm on will probly spin while trying to put it on. ur gunna need a impact. all u do is keep spinning it with the impact and it will catch and tighten up

    Cognito makes some serious Pitman and Idler arms.

    remove the arm from the center link, unbolt form the fram, and reverse procedure to install the new idler arm. Since the arm is pressed against the center link, you need an extractor tool (or a BFH, metioned below) to separate the two. Nevertheless, a BFH is never recommended.
