Pitman arms on a Sheppard M110 don't come off easy. The splines corrode into the sector shaft, the taper locks in, and anything you try to coax it loose with like a torch, pry bar, hammer with a long handle and a short fuse, usually ends up costing you the gearbox too. The 10389 is sized to the M110 specifically. No generic puller, no makeshift adapter, no hoping the geometry's close enough. It seats square against the shaft, grabs the arm cleanly, and pulls under impact power without putting any side-load on the steering box you're trying to keep alive. Pulls seized pitman arms without heat, hammering, or pry damage Rated for impact tools up to 3/4" for fast, repeatable removal Machined to the M110's geometry — no shimming, no fighting the fit High-strength steel construction holds its shape pull after pull, even on the rusted-in ones When the M110 shows up on the lift, this is the tool that gets the arm off and the truck back on the road. ApplicationClass 6–8 trucks and equipment with Sheppard M110 steering gears — most Kenworth, Peterbilt, Freightliner, Mack, and Volvo configurations running the M110.
