Adjusting a pete 379 trw steering box.

Adjusting a trw steering box without the special tool while mounted on the truck. I'm a trucker not a camera man so don't hate on the shakey video. #peterbilt379 #trw #steeringbox #peterbilt

I was about to replace my steering box and came across this video. Just saved myself more than a buck. Learn something new everyday. ☝️👍

Glad it could help. I just did this one 4 months ago so I knew it didn't have to be replaced yet thankfully but your not lying the box cost me 6 and change and I did the install. If there was labor involved it would have cost 1200 bucks easy.

Hell yeah. I was wondering if you could do this to these. Ill be doing that this week. After 5 grand in front suspension parts it still wonders a bit. Definitely need to tighten mine.

Why did you feel you needed to do adjustments? Any symptoms that made you think okay let me do adjustments? I have the back of the pigment arm moving a little when i pushed forward and back, between the steering box and the pigment arm moves.

[@lancianotransportllc2065]

I had float in the steering going down the road and excessive play in the steering wheel as well. This box was bad and eventually did need to get replaced under factory warranty, but the adjustment got me another month out of it.

Do you think 389 has that adjustment screw thing just like 379?

[@lancianotransportllc2065]

If its a trw steering box yes. But even if its not it should still have an adjustment.

[@Legendk379]

Yes found it and was able to fix it within in 10 mins.. this was really helpful and probably saved me few hundred bucks and a trip to the shop.. you’re awesome man 🙌🏻

This adjustment loosens ands tightens the free play on the steering wheel? What if I don’t have free play but my steering wheel feels heavy and bulky, will this help me make the steering wheel a little more loose?

[@gtdodgeviper]

I don’t think it will.

You may have air... if not you need a new gear box

[@lancianotransportllc2065]

Most likely your box or your pump is on its way out. Ide start with the pump since it's the cheaper option but check for air in the system before anything.
