    Hi guys,

    Need some help!!! Trying to replace the pitman arm ('04 2500HD). I was able to replace the idler yesterday. TI have 2 of the 3 bolts out of the steering box and the third loose. I have the p arm remove from the transfer link and the bolt off of the stud holding the pitman to the gear box. I have soaked it with PB blaster for 6 hours now and using a puller I can't get it to move. I even snapped a cast puller attempting. Not really excited about using heat, it could transfer into the steering box which could cause grief there. Any ideas? Turned into a bigger PIA than anticipated. :gunsfiring: :realmad:

    I just did my Pitman arm Saturday and it was a nightmare. My buddy and I ruined 3 pullers (2 cheapo's and 1 that looked similar to that Snap-On one). We ended up using a die grinder to cut the arm as close to the shaft as possible and then used a chisel to crack it open. Fell right off!

    Thanks for all the advice guys! I ended up removing the steering gear and taking it to a local shop. He'd never seen one so tight, but we got it off. Two words to the wise: 1. Come with the big guns on this project (harbor freight tools won't get an old nasty pitman arm off) 2. If you have to take out the steering, make sure to get everything alinged so as to not mess up your steering :)

    Good news is, the fornt end is as tight as one on the showroom floor!! Thanks again.

    usually I use an impact gun, put a load of torque on the puller, and then hit with a large ball peen. This removes even the stubborn arms.

    ......................and heat won't hurt anything if you use it properly.

    I always use a cutting wheel and an impact hammer with a chisel tip.
