How to Replace Pitman Arm 2000-06 GMC Yukon

You wanna keep in mind, when you're doing this job, after you're done, you're gonna wanna go to a local garage and have the vehicle aligned so you don't have premature tire wear.

Disconnect the battery. Disconnect the negative terminal. Use an 8-millimeter wrench. Disconnect that, just slide it out of the way.

You wanna make sure the steering wheel is centered, and you want to lock the steering wheel somehow. What you can do is take the seat belt and just go through the steering wheel and then buckle the seat belt. That way, it'll keep the steering wheel from turning.

All right, take the wheel off. We wanna remove the hubcap. Use a straight-blade screwdriver, slide that off. Use a 22-millimeter socket, take the lug nuts off. Remove the wheel.

I'm gonna take this panel off, use a 15-millimeter socket, take these bolts out. There's four bolts. Slide that down.

Take this cotter pin off. Just use some side cutters. Now, remove this nut. Use a 21-millimeter socket. So, now you can try to use different types of tools to separate this. I'm just gonna use a puller. You can try something like this or you can try something like a pickle fork to try to get it in there.

I'm gonna try to use a pickle fork now. Here we go. We're gonna pull this power steering hose off the steering box right here. You may have a clamp that's holding it on, this one happens to have a worm clamp. Use a 7-millimeter socket. If you have the regular style clamp, just use some pliers. You might wanna put a drain bucket underneath because you're gonna lose some fluid. Take that off.

Now I wanna take this steering line off, use an 18-millimeter wrench. It's not easy to get in there with a wrench. If you have a crows foot, that would work a little better. But just do the best you can.

So, our line is rusted at the top of the steering box and it's not breaking free. In our situation, I'm gonna have to take it off the brake booster. I'm gonna use a 16-millimeter wrench and loosen this up. But, ideally, if you can get it off the top of the box, steering box, then that would be ideal. And I can slide this line out from here. Now I'll just take this line out with the steering box. Just like that. And then, on the top of the steering box, we need to take the linkage that connects this to the lower steering column. There's an 11-millimeter bolt, take that out. Pull that bolt out. It's a good idea to replace this bolt whenever you take it out.

Let's just take a pry bar, get in between the lower steering shaft and your steering box and just pry it up to try to separate the two.

So, I'm gonna try to get this off the rest of the way from underneath. Take your pry bar, try to get in between that groove right there. Just try to hammer it up. All right, that's popped off. It's good.

Now we need to take these three bolts out. There's one behind the shields right there. Use a 21-millimeter socket. Take these out. All right, I'm gonna take the last one out. Just loosen those so they're loose like that.

[inaudible 00:04:53] steering box, just lift it up because you gotta pull that pitman arm out. Twist it sideways so we still have that line connected. And here we go.

Now I'm gonna use a 34-millimeter socket to take this nut off. Take that off. Now this is a dust seal right here. Just get a straight-blade screwdriver and just push it up. Just get that out of the way so we can put our tool on and put the pitman-arm remover on. Here we go.

Now there is four key ways for this to line up. So, install this the same way that the old one came off. Put the lock washer on, put the nut on, and tighten this up. And then do the best you can, put this in a vise and then torque this nut to 180 foot-pounds.

And then slide this dust boot back down. Just like that. Looks good.

Now I'm gonna send the hose up first. You know, if you were able to not have to have the hose connected, then you don't have to do this part. And slide the box in position. You wanna get the pitman arm through that steering bar...just like that. Make sure that's lined up first. Move this around a little bit and get one of these bolts started. And you can try to get the other one started as well. I'm gonna have to rotate this a little bit.

Now I'm gonna torque these bolts to 110 foot-pounds. Now put this nut on. And we're gonna torque this nut to 46 foot-pounds.

Now if the hole's not lined up for the cotter pin, you can tighten the nut a little bit more. It's better to tighten it than loosen it. And that looks good. A little more. Put the cotter pin in. Take some side cutters and just bend it...just like this. And trim the excess.

So, you just wanna make sure that the steering box, the wheels are straight just like it was when you took this shaft off. And just get this lined up. You can get it started while you're underneath. Or you can try to do it from up top.

All right, let's slide the steering shaft onto the box, or the gear. That's lined up. Now you put that bolt in. And do the best you can with torquing this, it might be a little bit better to torque this from underneath. You could get directly on it. You wanna torque that bolt to 37 foot-pounds. Okay, good.

Now I'm gonna run this hose back the way it came, up to the booster. And if you didn't take it off here, connect that hose down below.

All right, now snug this up. Now, if you have the ability to use a torque wrench, you can torque this nut, or the lower nut, on the steering box, to 20 foot-pounds. That's good.

Now install this hose. It goes to the cooler. And tighten this up, if you have a worm clamp, or use the hose clamp pliers. And just snug it up. And this cover, bolt's in. And tighten thee bolts down.

Now let's reconnect the battery. Give it a wiggle, make sure it's tight, and you're good to go.

Now we're gonna top off the fluid, take the cap off of the power steering pump. And then use a funnel, and check your owners manual, put in the appropriate fluid.

All right, so, I over filled this a little bit, which is okay. Now, with the front wheels off the ground and the cap off, you might still wanna put a bucket underneath. I'm gonna turn the wheel back and forth about 20 times. Slowly.

All right, we're gonna double check our fluid level. I haven't started the vehicle yet. And the fluid level's right there. Before I just suck some of the fluid out of there, I'm actually gonna start the vehicle, turn the wheel back and forth a couple times, and then recheck it and adjust accordingly.

Install the tire. Put the lug nuts on. All right, tighten these lug nuts down. I'm going to tighten them in a star pattern, or a cross pattern, to 140 foot-pounds to tighten the wheel down evenly. I'm just go around again, double-check. Take the center cap.
