axle nut size and speed sensor repl proc

[outrag1]

Hello,

Vehicle in question is:

1999 Chev Tahoe (Classic Style like 98 and earlier CK)
2Dr
4X4

I'm looking to replace the wheel speed sensor in the left front assy. I've taken the tire, caliper, and rotor off the vehicle at this point.

Can someone provide the socket size for the axle nut (34mm - 36mm maybe?) and also the 3 bolts holding the hub assy to the knuckle (15mm maybe?).

It would also be appreciated if I could get the procedure to replace just the wheel sensor. In other words, do I need to remove the axle nut and the hub bolts and the assy from the car? Can I just try and remove the two hub bolts holding the shield in place to get at the sensor?

Thanks - Bob
