I'll keep this as short as possible, believe me, its a long story.

I've replaced 2 faulty wheel bearings in my car. Did it myself. (both bearings and sensors bad). Still had a code. Used $110 autozone ones.

Took it to a dealer, they replaced both front bearings, said the sensors were bad. $1,000 later, it works for about 3 months.

Took it back, rear bearing, $500 later it works for 6 months.

Took it back again, waranteed front bearing, free.

Took it back again, waranteed other front bearing, free again.

Well its been a month, and im about to send it in again. ABS, svs, trac off. The regular wheel bearing deal. Both front bearings are under a 12 month GM parts and labor warantee. I tell them after almost $2,000 i cant afford to fix it anymore, so if its a waranteed bearing, i want them to replace it, but if its something else, forget it. Tech tells me even if it is a bearing, he wont replace it because something else must be going wrong and 'ruining the bearings.' He also lectures me that since his techs are all such trained professionals, he cant have them working for free (diagnosing waranteed parts). Says he cant run a business that way.

If this is really true, how the hell cant a techII figure out that something else is wrong? Could something else (ebcm, or whatever), really be causing all these wheel bearings to burn out? And am I wrong in feeling that after paying them $1,500 for waranteed parts, that they should stand behind them and replace them if theyre faulty?

Typically if a part is being replaced under parts warranty, the only thing that isn't covered is the labor. Unless a dealership installed it. In which case it should be covered completely.

Tell them to check the damn wiring or replace a jumper harness already. I believe there was a bulletin on speed sensor harnesses in the front of those N-bodies. Something about the wire strands breaking inside the insulation due to flex.

If the bearings aren't failing mechanically then I'd definitely look real hard at the wiring coming from them.

Here's that bulletin I mentioned. One of the first things that came up when I searched for "Wheel".

When servicing the vehicle with the VIN you entered, the following diagnosis might be helpful if the vehicle exhibits the described symptoms.

Condition/Concern:
91 - 05 JB, NB, or LB vehicles may set any one or a combination of front wheel speed sensor ABS codes as intermittent or hard failures.

Recommendation/Instructions:
If after inspection and diagnosis, using the applicable trouble tree(s), the cause of the fault is not readily identified, the most probable cause is often the wheel speed sensor jumper harness. Oftentimes, the harness checks good with the J 39200 fluke meter but will not function correctly when subjected to suspension movement, vibration, and flexing. Seldom will the above condition be corrected by the replacement of the EBCM. The listed part numbers are leads that incorporate a highly flexible "angel hair" that reduces down to standard gauge wire so that it may be properly spliced into the existing circuit. Standard gauge wire should not be used in place of these part numbers.

Please follow this diagnosis process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed. If these steps do not resolve the condition, please contact GM TAC for further diagnostic assistance. This diagnostic approach was developed for the vehicle with the VIN you entered and should not be automatically be used for other vehicles with similar symptoms.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.

I ended up bringing it in after arguing with them for a while, and they finally agreed to cover it. They said it was the wiring, and that it was caused by vibrations from living on a dirt road. This is total bs, since it throws codes when its parked and idling, not driving. Anyways they pulled the wires out and cleaned all the connections. They suggested if it happens again to replace the harness. If thats the case, ill just do it myself. They told me about that same bulletin, but thanks for showing me that.

Those harnesses are a little on the pricey side but well worth it. Its really easy to replace them as well. Just follow the harness to a breakout and splice in where accessible. They even come with butt connectors. Just make sure to maintain the twist in the pair otherwise things might get screwy.

Does anybody know if there's a third party company out there that makes these jumper wire harnesses? I checked with a local dealership, and they told me $160/$180 a piece, depending on the side. That seems a little ridiculous for an ABS jumper...

Anyways, I figure I'll check my connections before I go that route... Where exactly do the ABS wires end up? I can follow them from the wheel speed sensor up the control arm/trailing arm, but I lose sight of it once it goes up under the engine... can anyone help me out?

Thanks.

hey this is a back door way of getting 25% off at the dealer if all else fails.

Just call and pretend your mechanic at an independent shop and tell them what you need and you better sound liek you know what your talking about. And before the shoot you a price ask for wholesale pricing. Its 25% off of list.

To above, Alot of dealers use POs now for their independent orders....

If you can't accept a PO or don't already have an account, forget it.

Or you could just order them from gmpartsdirect.com and get wholesale pricing without any hassle. ;)
