How do you replace a wheel assembly on a 2000 Montana with out cutting the abs wires?
You need to remove the hub assembly and replace it. It consists of bearing, studs and speed sensor. The wires are attached to a connector which is clipped to sensor shield. You cannot remove sensor on Montana without removing the hub. The sensor is a part of assembly.
Wheel bearing is part of an hub assembly. Remove wheel, remove caliper & rotor. Disconnect speed sensor, unclip connector. Remove shaft nut in front & 3 bolts in back - replace with new hub/bearing/studs/wheel speed sensor assembly tighten to spec. You need to also remove the big shaft nut. When replacing make sure axle nut (33mm) is torqued to spec. [160Nm (118lb ft); hub bolts (13mm) torque spec: 130Nm (96lb ft) - 2000 Montana]
The wheel bearings in the vans are "integrated" as part of the hub assembly. This is because of the wheel speed sensor, which are part of the Anti-lock Breaking System (ABS). In order to replace the bearings, you have to replace the entire hub assembly. These are not cheap, as a result of the included sensors. Sorry about that. Good Luck, Greg A.
