Default Dana 60 TJ, 6.0 Vortec steering help!

I recently did one-tons into my 99 TJ. I've been wheeling it and very happy with everything except the steering. I am running a 6.0 vortec with the factory saginaw pump that came on that engine. Utilizing the factory 99 TJ gear box. Running high steer on the axles, all DOM w/heim joints.

The jeep drives great but is an absolute monster to steer. At low idle speeds it is very difficult, often two hands required. It it's in 4x4, two hands absolutely required and have to give it everything I've got to make it turn. I have already performed the standard flow/ pressure mods to the pump. Anybody have any ideas?...or is hydro assist my only way out of this? Thanks!

Hydro assist. If you have a front locker or very large tires I'd say it's almost a requirement.

something isn't right. I wheeled for years (and was a DD) on 37s with the stock pump and 4.3

it wasn't easy to turn when bound up, but drove just fine on the pavement. I did upgrade to a PSC box at one point and that was better.

sorry I can't help more. I'm no steering expert

It does drive pretty well on pavement....as long as it's moving, and off idle.

Part of it is you need assist, part of it is the gm pumps suck, especially at low rpms. Even with a fancy psc pump (stock style)my steering still sucks at idle even with full hydro.

I have a stock GM pump on my full hydro and it works fine. I'm in the hydro assist or full hydro camp. Honestly, if you can afford it, I would make the jump straight to full hydro.

OK, this is all new territory to me, I'm going to need to get educated on this. What's the major difference between full hydro and hydro assist? My rig must be driveable, is that possible? Is there a recommended source for a kit or most parts? Thanks

Something doesn't quite add up here. My tj has a 5.3 with a Dana 44 and steering just like yours. On 35" tires with the Durango box at idle I can turn my wheel with 1 finger

Mmm.. wide boggers. What's the backspace on the wheels? I'm guessing low side on the backspace based on back of rim and rotor.

I'm with the others, with that tire combo, I'd recommend full hydro.

Two things you're going to want to do. First, go hydro assist or full hydro. West Texas Offroad is the place to go for hydro assist. They're cheap and do great work, also very good customer service. My box will be back from them on Monday.

Second, find a way to make your high steer arms double shear. The forces put out by your steering box and a hydraulic ram are going to bend and break that bolt and your arms eventually. Save yourself that headache right meow.
