The attached picture show how I pulled or pushed on the hub so that the movement in and out of the wheel carrier is within the tolerances specified in the Service Manual.

great write up- I did this once w/ advice from a tech at the local dealership- he said forget the dial gauge, just get it real tight until you cant feel play. so I did that.

One thing I did was use a bit of allthread and some big washers to pull everything together on assembly.
also< i rented the free slide hammer/ hub puller from autozoo. the hub adapter doesnt fit perfect, but worked.

then 10 months later, I re-did it w/ a dial gauge and new bearings. you really need the gauge, IMHO.
it is really a tite setting. FWIW, the second time around only took me an hour- I already had a good bearing installed on a hub. the first time, I had a shop remove/ install the bearings for $12/ea.

Dave,

Excellent write up and excellent photo's. I think you out did yourself this time, perhaps an even better write than your R&R evaporator A/C write up.
Well maybe.

Eric

A note for installing the axles back into the hubs. I could not get the axles to go all the way back into the hub. Tried pounding the axle from behind ( on the metal can). No luck. Bought an all thread rod (M8 1.25 X 3ft ) at the local bolt supplier with 2 nuts and a large washer, $5.75. Tried creating a slide hammer to get it to install, still would not go all the way in.
I finally inserted the all thread into the axle. Slid a plate over the rod and installed a washer and nut. Turned the nut with a box wrench and the axle slowly slid into position. Replaced the axle bolt, sleeve and a new washer and torqued to 30Nm as per the manual.

Dave

between the FSM (horrible poor rez pics and confusing terms) and a couple of quotes from mechanics($400-500 each side) I have been a bit bummed out about this job. My bearings bless them are running fine but there is a LOT of play and it is going to have to get done.
After reading your article I now believe I CAN DO THIS,
Though I am not at all sure I want to do this
