Update on rear brake/axle sound .. whine sound ...
Can any of you tell me if you EVER hear ANYTHING coming from the rear when you brake hard? We've been on a trip for a week .. left the H3 with the dealer/service dept ... hoping they could find the problem with the SAME left rear 'grind' sound when I come to a quick or hard stop. As you may recall, they had the H3 for almost 2 weeks trying to find the problem ... they replaced the pads and resurfaced the rotors. The sound went away for 12 days and came back. There is a periodic whine .. and the same 'grind' sound coming from the rear. I took him for a test drive a week ago AGAIN and he heard it .. saying it could be the rear axle or drive shaft. I called the Service Manager today (Friday) for an update. He said he opened the axle and didn't find any damage or metal. He said the sound I hear is normal on all H3's. Of course, he didn't say that when he took the test drive with me last week and said he heard a definite problem. Then he said maybe I am braking too hard when I'm 'trying' to hear that sound. I have an automatic. I hear the sound when I come to a quick stop. If any of you have an automatic .. could you PLEASE do a test and come to a fast stop and listen hard?? Do you hear any sound like a grind from the rear just as you come to complete stop? I'll be seeing him on Monday for a test drive again. Why I don't know. He said the sound is there if you brake hard. I told him if I hear it, I will not accept it. Any advise, anyone?? Should there be a sound? Should I contact someone from Hummer? We won't be back home til Sunday. AGH!!!! Thanks.

Re: Update on rear brake/axle sound .. whine sound ...
My H3 would make a loud groan (not really a grinding sound) just before coming to a complete stop when braking hard. Mine sounded like the anti-lock brake unit was paulsing the brakes just before coming to a complete stop thereby creating the noise. I don't know if this is what you are hearing or not. I had it at the dealer twice for this problem. The service manager assured me that the noise I was hearing was normal for the anti-lock brake system used on these vehicles. The noise is gone now I traded the H3 for a new H2 SUT

Re: Update on rear brake/axle sound .. whine sound ...
Nice way to get rid of the noise, ranngerross ... trading in for an H2! I guess mine sounds like a groan more than a grind .. hard to tell. Alot of the folks here had helped me before (about a month ago) when I first had this problem. They're probably tired of seeing my samo samo post. I'm frustrated with this problem. It feels like the dealer has had my H3 off and on longer than I've had it. I'll see if the Service Mgr mentions the anti-lock braking when I go in on Monday. This sound, though, had FIRST started about 2 months ago and then got worse. I bought the H3 the end of last July.

I've had my H3 for a year (20K miles now) and never experienced this braking noise. Normal?

Re: Update on rear brake/axle sound .. whine sound ...
I bought my H3 middle of June last year. The first time I noticed the noise was the 2nd month of ownership. The noise may have been there earlier and I didn't notice as I was enjoying the monsoon system. The noise reminded me of a sound from brake pads which have been overheated and developed a glaze on the surface. I live in an area with heavy traffic and bad drivers. I had to get on the brakes hard a few times - don't know if this is the cause of the problem or not. I have seen mechnics sand the surface of the pads and rotors to eliminate a glazing problem. You may ask your dealer to check for glazing and try this fix if they don't have any other suggestions. Good luck and let me know what you find out.

rangerross, could you, as the driver, feel the problem when braking? I not only hear it, I can feel it in the pedal when it happens. I'll post what happens on Monday. Thanks again. Thanks, Steve-San Jose, too, for your input.

I've engaged the antilocks under hard braking. That has a grinding feeling and you can feel it in the brake pedal.
I just mention this because I don't see where's been brought up before.

You guy's need to move out of the city's and get away form the 'Can speed bumps and bad drivers. Come out here and play with deer, badgers, fox's, cow's and the big a$$ tractors that are heavier then most semi-trucks. Nice open county. Best of all, low population. ummm, nevermind stay in the big city's. I don't want to share.
