Toyota knuckle centering tool variants (1 Viewer)

[tohox]

Hi,

I've read somewhere on this forum that the Toyota SST used for centering knuckles was a universal fit between LC series and that it was just a matter of using the supplied adapter bushing or not depending on the axle you have. I don't know if this is true or not.

I've just purchased the 09634-60014 model and the shoulder bushing that holds the scribe end is loose inside the axle bore by several millimeters but fits OK inside the spindle (without the bushing).

The FSM I have mentions 09634-60013 which is no longer available so I figured the 09634-60014 must be a replacement. Unfortunately the Chassis and Body FSM I have is for models 3 years after mine (1994 instead of 1991) so I don't know what tool number is appropriate.

What would the appropriate SST model number be for a 1991 PZJ77-MNS ?

If any of you have a similar centering tool I would be curious to know what the OD of the shoulder bushing is. Mine is 39.90mm which was probably intended for a 40.00mm bore. I think mine is closer to 50mm.

Much appreciated!

I know the ones for the 60/40 are different than that used for the 80.

Would you happen to know what the tool numbers are for these?

 

[ceylonfj40nut]

Sorry. I don’t. @TRAIL TAILOR used to make some for the 60 series and might know for that model.

40/55/60/61/62 and early 70 are the same tool. 60013 and 60014 are same tool from measurements.

I make a reproduction.

What years are considered early 70's? 1984-?? Should the 60014 fit inside a 1991 PZJ77 axle?

Thanks!

If your knuckle bearings are -17001’s then the 60014 tooling will work.

If your knuckle bearings are -20003’s then the 60014 tooling will not work.

I believe my trunion bearings are the 90366-17007.

Currently the vertical portion of the 60014 tool fits fine through the trunion bearings and I was able to measure the total shim thickness required (dimensions A, B and C).

It is the scribe portion of the tool which I can't get to fit inside the oil seal cavity to find dimensions D (and eventually E and F). The 90310-35010 oil seal which goes into this cavity is 10mm wider than the tool's bushing OD.

I'm considering machining my own shoulder bushing with an ID compatible with the tool and an OD compatible with my axle...

What is the unicorn SST sleeve that will work?

When is this tool supposed to be used please. I have watched a number of "70 front end-rebuilds" on u tube and never seen any kind of centering. Are they just winging it and hoping that the new bearing is close enough to the old one size wise. Their most sofisticated tool seems to be a small levered torque wrench or a fish scale for the pre load.
What am I missing? I need to do my 2007 4.2l 76 wagon some time.

You don't need to go through this procedure unless you actually change your knuckles or you have lost/misplaced/mixed up your original shim arrangement. If you are simply changing bearings, seals, birfs or gaskets but keeping the original knuckles and shims you don't need to go through this procedure.

So, is this the part that you call the knuckle ??

I'm not familiar with this particular diagram or model but I believe that the part at the bottom which is cutoff is probably your knuckle.

Here is what mine look like (red arrow).

I know that’s a parts diagram, but are there only shims for the top bearing?

No. I believe that depending on the D measurement given by the centering tool, shims may go at the top, the bottom or both.

I know the ones for the 60/40 are different than that used for the 80.

From what I understand there's no centering tool for a 80. They shim on the top only.
Just reuse the factory shim good to go.

 

[ceylonfj40nut]

@Broski, what if you don’t have the factory shims? I recall @CenTXFJ60 indicating there is an 80 tool. Pinged him.

I have never heard of there being more then one shim and they only go on the top so there no centering.
It's about getting the preload right, If the trunnion bearing aren't to tight you should be fine with out the shims.
If @CenTXFJ60 has info that contradict this please let us know.
Or maybe one of the gurus can chime in and share some wisdom on the subject

80s Knuckle install per FSM

 

[tohox]

That's a different tool and process than the one used for centering the knuckle. This one is apparently used to support the trunion bearings while reassembling the knuckle but I've never felt the need for it and have always managed without one.

The tool and procedure used for determining total shim thickness, where they should be installed as well as adjusting trunion bearing preload on my truck is the following:
