Setting preload on 47# kingpins

[Tooheys]

Ive recently pulled down my swivel hubs on my 47# ute and I'm a bit sus about the preload on the swivel hub because one side had heaps of shims and the passenger side had only some on the top. Ive pulled the swivel hubs apart to change the steering arms to HJ75 as part of the 60# powersteering conversion im doing so im thinking these arms might also affect the preload. I did a search and found this http://www.outerlimits4x4.com/PHP_Modul ... ngpin+shim. So my questions are:

1. When i reassamble without wiper seals what is the torque for the 8 bolts that holds everything together?
2. Am i looking for No resistance in turning or a little bit of resistance?
3. Is it best to add shims to the top then to the bottom alternatively until i get it right? or just add to the top or just add to the bottom?

So my questions are:

If you are referring to the bolts that secure the stub axle to the swivel housing, the torque is 47 Nm. If you are referring to the 4 studs that secures the steering arm and the 4 studs that holds the lower bearing cap, 96 Nm

2. Am i looking for No resistance in turning or a little bit of resistance?

A little resistance from the steering arm and the bearing cap pressing on the swivel bearings.

3. Is it best to add shims to the top then to the bottom alternatively until i get it right? or just add to the top or just add to the bottom?

Assuming the shims were installed at the factory in the manner you described, install them back in the exact same location as you found it. These shims are there to center the swivel housing relative to the axle housing so that your inner axle seal would wear out evenly. To determine the number of shims necessary on the top vs. the bottom, you need a genuine Toyota Special Service Tool (part number 09606-60020). If your axle seal had been wearing normally, it is much easier to keep the shims exactly the way you found it.

thanks mate that makes sense. If i do have to add shims and since i dont have the service tool do i just add them evenly to top and bottom so that i dont stuff up the alignment?

If your axle seal hadn't leaked prematurely, I suggest you put the shims back in the same order you found them as that was how the factory, or at least the last person who last put the swivel back together, determined to fit the best. There can be minor casting and machining variations on the swivel and housing that made it necessary to shim in the manner you found it.
