My truck already was in the shop 3 1/2 years ago for the recall and within the last year I've replaced the wheel bearings anyways, which came with new sensors. I don't believe the dealer will do the recall a 2nd time for free

Swhitney is right. The problem is called "unintended low speed ABS activation". There was a recall for trucks in the "rust belt". Undo the torx screw that holds the ABS "reader" to the hub and pull it

"Driving" it on the lift can make it act up but honestly the scan tool won't pick up the sensor being corroded- if there were a fault/code stored the ABS light would light up. This is just one of thos

I was informed on my 04 that it's not a recall, just that there's a TSB issued for it.

 

I just did the repair that GM says to do, and found it to be quite easy. The sensors are a pain to pull completely out, they come about half way and then got stuck and I had to gently use a pair of pliers to get a firm grip and get them the rest of the way out. I can see where some people have had them break off.

 

Then it was just a good sanding job and some grease and put it back together.

 

For what was supposed to be a quick repair, it was. And other than the fact once I had the rotors off I discovered I needed new rotors, it was free to fix.

 

Took my under an hour to do the actual sensor fix...the hardest part was loosening the bolts on my brakes, they were pretty tight. After doing the fix, I havent encountered the issue that I was, so I recommend attempting the fix yourself if you're even remotely mechanically inclined, as I found it very simple and self explanatory.

One wheel bearing & sensor is brand new and the other side I already cleaned up with the same issue. Something else is going on but I haven't had a chance to schedule an appointment to get it in to the dealership.

My truck just started doing the same damn thing. Low speed, coming to a stop, and the whole truck vibrates when the antilocks kick in. Our of warranty too. Nice.

Found out it is the passenger side sensor not reading the correct speed. It is an aftermarket wheel bearing that is about a year and a half old. I took the stock sensor out of the old driver side bearing and put it in the passenger side and it still acts up. I had the dealership tell me what was wrong, but I wasn't gonna shell out the money for them to put a gm bearing & sensor in it. I'm afraid to spend another $115 on an aftermarket and not fix the problem.

Are you more scared of paying out what GM wants to fix it...or rear ending someone and having to pay out the cash for an insurance claim?

 

Bet GM isn't charging you anywhere near what your insurance will charge you, for both your deductible and your increased rates for the next few years.

I read somewhere that people have pulled the fuse out as a temporarily fix. But i am not sure if that would work in your case. You would not have the abs of course, but would be safer than the alternative.

I have the fuse pulled for now so that i don't have any accidents, I had to many close calls and pulled the fuse as it is safer than the abs kicking in every stop

Got the truck fixed. Took it to dealer finally and they told me it was actually the passenger side that was not reading to correct speed. I put a new bearing in this afternoon and after a 5 mile trip around the block, I never had any problems. I had put a different known good sensor in it over the weekend and that hadn't fixed it, so the bearing was next. That bearing was only about a year and a half old, but the tone ring inside must have been messed up in some form, but nothing I could see. Oh well, ABS works now and I don't have to stare at the lights on the dash.

I'm having the same issues. Anyone have pictures of what I should be looking for? Or a link to the TSB?

 

Mine's an '05, but I don't think that it matters....

A shop will be able to read the wheels, and see which VSS is not lining up with the others. I just had this on my moms saturn vue red line. For the saturn, I had to replace the whole hub, as it is part of the assembly.

I have the same problem on my '06.....I asked if GM was going to expand the recall being that a number of newer vehicles are experiencing the same issue as the older recalled vehicles...I was told "No"...so I reported the problem here ( NHTSB )...maybe if enough complaints are lodged, they'll expand it. Feel free to join me.

it is not a recall just a TSB and most dealers will not perform this for no charge because they don't want to get stuck with the bill if you are out of your 3/36k warranty.

 

I had the same issue with the cloth interior TSB on my 07 GMT900 which I purchased with a GM Certified Warranty. The dealer would not perform the TSB so I called the GM warranty customer service # and told them what was going on. They contacted the dealer and within 24 hours they called me back and said the dealer would take care of it.

I hate to bring up an old thread but this may be the answer to my problem. When applying the brake a a low speed and hitting a bump the abs would kick on and it was like I lost brakes completely. Did it once or twice last fall but then did it in the a few days after christmas when out plowing and ended up rear ended a car. Plow prevented any damage to my rig but messed up her bumper and now my insurance just went up abit :crazy:

Anyway now that the weather is getting better I definatly would like to get this fixed. What exactly to I have to sand/clean up? I keep hearing about a possible recall for this but can't find any good info. Truck is a 2000 3/4 ton Silverado and I'm in Vermont so I'd assume that would be in the "salt area" that I heard mentioned

      Of course refrain from political debate but I myself have very dismal hope for what is all going on up here every where we turn so I nodded my head when I saw this joke.

      I'm looking at carpal tunnel surgery on my left hand and lumbar fusion.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      While waiting for parts I have been working on installing the AC compressor, new accumulator, and orifice tube. Also changed out the high side ball valve (original). The orifice tube that was in there wasn't too bad. Slightly dirty, a little bit of junk, but not blocked. Glad I changed it out.   The accumulator, which should have been a 5 minute job, may have just burned $50. Put some PAG in it, wrote the date and mileage on the side, fresh o-rings and gooey'd up the threads and rings with Nylog. Got everything connected and snugged and was going to vacuum down the system, and....   My manifold gauge won't fit on the port. It's not an R12 service port. It LOOKS like an R134 service port but the diameter is a hair too large. There's a sticker on the accumulator that says it's designed to be used with R12 and R134a systems only. So it's not R1234yf. Even if I reduced the diameter slightly with a file, the shoulder on the port is too large so the quick-connect valve won't lock on. I'm stumped. It's going back, and 50/50 on if they'll give me a refund.   Also, I did a fuel pressure test.... Key on, the gauge spikes to about 60psi and quickly bleeds off, like 2psi per second. The fuel isn't going into the plenum, no smell, starts fine, so I'm guessing there's a bad check valve in the pump and the fuel is just draining back into the tank. oh, hell. But, it shouldn't be a problem, pump primes just fine and the truck starts right up. It just means I can't really ever use fuel pressure to verify a leak at the injector or intake.

      SERCICE ESC message?

      By No F-bdy Bs · Posted

      Got this yesterday out of nowhere. Truck is a 25',6.6 gasser with 8k miles.  Only semi anomaly is that the truck had been sitting, uncranked for 6 days. Elec Stability Control showed immediately upon cranking, not while driving. No drivability issues, just the message. Battery didn't seem to be weak when cranking over.  I drove it, killed it, let it sit a few hrs with no avail.  Truck is 100% stock. No damage.
