1997 blazer 4x4

A friend took his blazer into shop complaining of noise--said it sounded like a wheel bearing--I did not get a chance to look at it.
Shop said yes, right front wheel bearing was bad--cost to repair was $600!! Shop said a "sensor" needed replaced and that was the expensive part. Anyone know what "sensor" they could be talking about?--seems high!

Most likely an ABS wheel sensor. Depending on the cost of parts and the repairs needed, it sounds a bit steep.

On those vehicles the wheel bearing and antilock wheel speed sensor are 1 part with a wiring harness attached also.The part should be around 400 bucks.Labor about 1 and 1/2 hour that depends on the hourly rate at the shop and the time for diagnosis.So the price while a bit scary may not be out of line.

yep, just saw his invoice, parts were over $400, and with the labor rates around here--$600 is not out of the question. I was not aware of the sensor and bearing housing as one piece--thanks.
