How To Install A Blue Top Steering Gear Box (GM/GMC Duramax)

Alright here it is new steering gear box, and pitman arm! It was an awesome install with two people (highly recommend). Add a little more time if you are doing it from the ground, but it took us about 2 hours with lunch, and of course BS’ing. Dont be afraid to tackle a job like this very doable!

Project Farm did an independent test/study on penetrating oils, Kroil is good but is actually outperformed by Liquid Wrench. Liquid Wrench is also far cheaper.

Luckily the power steering fluid that my old gearbox was leaking acted as a lube for all my bolts. Made the job much easier lol

[@dmaxxd94]

Same lol

[@papabapyro]

Just found your channel. new sub. Thought it was my hydro boost leaking, but gearbox/pitman arm seal pissing bad. Thanks for calling out the wrench sizes. I'm old(64) but after watching your vid I think I can handle it myself, I do have a lift ;) I flush my fluid every 30K. Cheers

[@markthomas4083]

After my nasty comment. I need to follow up with a thank you. Very detailed video, appreciate the tool sizes provided.

[@bmxrideranton]

Looking forward to that review! The steering in my 03 is sloppy and I’ve been looking at getting a blue top. Awesome video as always!

[@DIYDiesel]

Thank you! It will be up next week for sure 👍

[@lucasseymour869]

Hopefully you have better luck than I did with my 04 lly. Installed 2 different red head steering boxes and both had different issues. Put stock one back in and no problems.

[@DIYDiesel]

Ya I’d stay away from red head. If this blue top fails we are just going straight to PSC

[@lucasseymour869]

@@DIYDiesel I will be waiting on a review. Lol

[@DIYDiesel]

@@lucasseymour869 lol next week 👍

[@lbzhonest5984]

Great video bro

[@DIYDiesel]

Thank you! 🤘🏼

[@Luistdelgado7]

Hey brother I’m looking to get a great box for my lb7 did you recommend the blue head ?

[@jhurley12]

For anyone doing this, you need to stabilize the steering wheel so it cannot rotate, most people use the seatbelt. If the steering wheel rotates beyond the clockspring range, it will break and you have a pain in the a$$ project on your hands.

[@rogree77]

How long did this job take doing it alone?

[@DIYDiesel]

A couple hours

[@donatotaa3713]

How much do you charge for installing my gearbox for hummer h2 2003

[@daflea66]

What size tubing for the flush hose? 3/8"?

[@Nameless_rat]

Bout to put one on my 05 2500hd, I've been reading online that the 2500HD are always 3 master splines, has this been the case with the ones youve worked on?

[@DIYDiesel]

Yes they are 3 spline. Unless you order a PSC that will be a 4 spline so you will have to get a 4spline pitman arm 👍

[@Nameless_rat]

@@DIYDiesel I was wondering about that, im replacing the pitman arm, idler arm, the idler arm mount and both tie rods at the same time and was wondering if I couldnt just order 3 spline anyways and convert it even if it was originally 4 spline, seems like the splines have nothing to do with strength if the 1500's have 4 and HD only has 3

[@05_Dmax]

Whats te difference between blue top and readhead?

[@DIYDiesel]

To be honest I can’t speak on it I have no clue I just went with them due to customer service

[@05_Dmax]

@@DIYDiesel was that for your personal truck if so how you like it im in the middle of building up my front end and never even seen blue top till your video

[@robboblitt6056]

Blue top still good my guy?

[@DIYDiesel]

Absolutely 👍

[@ThaddeusJBrown]

Guessing this is much simpler on a gasser too. I got a hard to the right steering issue when I am at parking lot speeds or sitting still. I'm going to try to bleed the system first, if that doesn't fix it it's gearbox time I already know lol. Do you have to have the truck running when you're moving the wheel from left to right? I'm going to put it up on jack stands in the front and try to do it that way.

[@DIYDiesel]

The process is pretty much the same as the ifs is across all there trucks. We had the truck running when bleeding/flushing it yes.

[@buddyrebel_Garcia]

BP blaster is better

[@DIYDiesel]

If that’s what works for you 👍 keep using it.

[@buddyrebel_Garcia]

@@DIYDiesel lol Im just trolling you lol heheheh

[@DIYDiesel]

@@buddyrebel_Garcia lol gotcha hard to tell sometimes

[@buddyrebel_Garcia]

@@DIYDiesel lol it’s all good. I actually use both

[@sean.g4516]

Blue top or red top ?

[@DIYDiesel]

I can truthfully only speak for what research I have done, and the blue top we currently have. I wouldn’t even think of red top (redhead) I would just order a blue top, if I didn’t want to spend the money on the PSC 👍

[@sean.g4516]

@@DIYDiesel thanks, and how does that kryptonite pitman arm feel did it help tighten things up as well? I'm thinking of getting the same sit up for my Silverado 1500

[@DIYDiesel]

@@sean.g4516 it did amazing. You also have to make sure your idler arm is in good condition because you could do all that, and then have a bad idler arm. Possibly seeing no improvement.

[@sean.g4516]

@@DIYDiesel yep just replaced my idler arm and bracket with the moog hd arm.

[@DIYDiesel]

@@sean.g4516 nice! If your going to do pitman arm, and gear box I would suggest also getting the cognito support kit 👍

Crazy to pay 35$ for some spary lube,rip off

[@DIYDiesel]

🤣

[@frankking2347]

Video could have been half as long if you ease up on the constant penetrating oil commercial.

[@DIYDiesel]

Part of when you gain a sponsorship 🤘🏼 wouldn’t take it back I met, and worked with some amazing people when I was doing that sponsorship.

[@markthomas4083]

Shut up with the penetrating oil commands, please.
