Can't get the pitman arm off. Help?

Can't get the pitman arm off. Help?

Postby Badmunky [OP] » Jan 14 2020, 3:16am

Trying to remove the pitman and idler arms from my 2015 Silverado 2500 and I can not get them off!
Nether will come loose from the center link.
And I cant even get a tool in there to get the pitman arm off even after unbolting the steering box.
Suggestions?

Bolt the steering box back on and.....................

There are pullers made specifically for the job your doing.

See if the local auto parts store has one to loan or rent. Or buy a cheap one (China) that hopefully you can get at least one use out of it.

If I had the correct one for these trucks I'd ship it to you to use for this job. Having the right tool always makes things go much easier.
Still may need to hammer the joints, with tension on them from the puller, to break the rust free but it is very doable.

Good Luck with it.

I rented a puller from AutoZone for $15. I used it like three times in one week and decided it was worth $15 and kept it.

There is a cross member that clears the steering box shaft by less than 1 inch in the way of getting any puller I have ever seen on the steering box.
With the box unbolted I have some movement but still nowhere near enough to get any puller I have or have ever seen on this thing. :(

I have 6 pullers here. NONE of them can get in here to get the thing off. :(

Every video I can find they say "Now remove the pitman arm" and then in the next shot its off and they NEVER show how they got it off.

I can not for the life of me figure out how to get this thing off. I f it would let go of the center link bar on the other end I am sure this would be much easier on me but neither end will let go. :(

Do you have any forks to remove balljoints or tie rod ends that might help you remove it from the center link.

I have few different Snap=On forks and a set of different size forks that fit on my air hammer to really give them a work out when there stuck and you can't use heat to remove them. I use Oxy/Acetylene when I can to expand stuff.
But obviously you can't do that at the pitman arm on the steering box without melting the shaft seal, etc.

I maybe wrong,, I can't see your situation. But I replaced a pitman arm on a duramax 4x4, I removed the two front bolts on the steering box, then with a large pry bar moved the steering box up enough to get a puller on the pitman arm,, I DID Not remove the steering box,, just the two front bolts and loosen the one closest to the cab.

A few not so cheap but worth it tools...

Also, you can cut it with a die grinder to release the tension around the splines. Takes a while and maybe a few cutting disk. Remember to use safety squints!

OK guys little update.

It's all apart! I just need to do some prep and then put it all back in tomorrow.

Here is what I had to do.

First of this puller would NOT remove the pitman and idler arm from the center link.
I actually bent the crap out of it trying. :shock:
386911

This puller on the other hand works GREAT and they just popped right out.
386913

And that let me remove the center link / tie rods from the truck.
386915

Next was to deal with the pitman arm. That thing is in there tight and there is very little room.
386909

I unbolted the box, then removed one bolt holding the hard line to the frame in the engine bay so I could actually move the box where I needed it. I then placed a board in the engine bay with a strap on it and lifted and rotated the box where I needed it.
I did first try the method others have used to remove only 2 of the bolts and then rotate the box allowing you access to the get the puller in place. This did not work on my truck.
The box would not move far enough before hitting the fan shroud and brake lines. Mine is a gas truck, so that might work on a Diesel truck. But it does not work on this one.
386919
386921

Then I was able to remove the pitman arm with this puller.
386923

Took me a while but I got all apart. Was getting late so I called it a night. I will put it all back together tomorrow. Then I get to order some more parts.

I found my front shocks are leaking.
And my drivers side upper ball joint has some play in it.
So Ill be ordering those parts Friday.

Just need to decide on new upper control arms now.
Im going to do Rancho 9000 shocks.
