Thread: 2000 Grand Prix GT, ABS Pump gone bad, Right Speed Sensor

well if we are getting back codes for ABS Hydraulics and Electrical then fixing the speed sensors are not going to change anything. And if i wanted to do that on my own i wouldn't even know where you begin. I realize everyone in here might be mechanics or have experience but i don't have the know how/knowledge or the tools to replace two hub assemblies and feel confident enough about it to let my wife and kids run off with it and know that they will be safe.

Yes and no. The way I see it, your ABS is cycling, which means it is working, and a new module is extremely expensive, so changing the two bad bearings may be your only problem. If not, then look at the module.

And being that you need a shop to do the work (which I get), and the quote you got is very high, I would get a second or third opinion for said labour. There #'s tell me that they are charging top dollar for the bearing, and possibly 2 hours of labour.

I just picked up the car and the ABS had 5 fault codes for ABS pump failure and right front/right rear speed sensors. (no idea on the actual codes). So to confirm i could drive it around for a bit and see if i can get the codes and then come back but no reason they would lie about that - they've been good to work with thus far. In other words, in this case, simply replacing the sensors wouldn't keep the ABS from cycling and then going off.

Here is the breakdown on the estimate that i did get though. I assume all new parts here since it wasn't noted otherwise:

1. Replace ACDelco ABS Pump Assembly/Modulator(w/Traction Control): Part: $1,100, Labor: $270.40 = $1,370.40
2. Replace Right Rear Wheel Hub with ABS Sensor(sensor is bad but bearing is good): Part: $230.53, Labor: $157.50 = $388.03
3. Replace Right Front Wheel Hub with ABS Sensor(No Signal from sensor but bearing is good): Part: $215.46, Labor: $201.50 = $416.96

The part prices for the hubs are not that far off of your $150 mark since they are new ( i assume you were talking about used). Not sure what they charge per hour though.

My #'s are for new. Those labour prices are crazy. Do you know their labour rate? Looks like they are around $100/hr. I have to say, that front bearing labour is rediculous. LOL

all i am saying is is that if there are 3 different codes coming from the ABS module itself - and 2 speed sensor codes - then obviously i don't know how fixing those speed sensor problems are in any way related to why I am getting 3 codes for the module.

they also warranty their parts and labor for 2 years after the work is done so don't know how or if they is factored into the labor rate.

the other thing that I just thought of is that all their mechanics work on foreign cars as well as domestic so their pay will probably be higher because of that. I know I've seen mercedes, porsche, audi.. etc in the shop when I've been in there.
