Hello, I have a 2007 Silverado and am experiencing two problems with it. Problem 1 there is a noise coming from the rear of the truck, either from the leaf spring of rear end, couldn't really tell. Problem 2 is intermittent. When I start the truck sometimes it will rev up to bout 1k to 1500 then shuts off and service air bag light turns on. It does will do this a time or two then starts. Today it took 3 times before it would fire. The thing today, my girlfriend had drove it to pick me up and shut it off. It had maybe been off for 5 minutes when it did this. Thanks, sorry for the long post.

Does the clunk happen at a light? Might be the slip yoke. Common with gm trucks sounds like a bark and feels like someone bumped into you.

Really hard to diagnose without being there could be a lot of things I would start with u joints and have a friend walk beside you while you drive to see if you can pin point it.

 

Good luck others will chime in this forum is great!

Took it to Autozone and they said they couldn't scan it since the CEL wasn't on. I pulled the neg, see if that clears the codes and maybe fixes the problem. Still working on the noise. Thanks

That's crap, I've had mine checked without lights being on. If they have a good scanner then they can scan regardless. Hope you can get truck fixed quickly, I can understand the frustration.

Thats what I was thinking. I think I may have the noise half way diagnosed. I think its a wheel bearing going out. Going to check it this weekend on the lift.

autozones scanner does not have the ability to read airbag codes, you will have to take it to a shop to have it read.

Any news on the clunking? I am hearing some clunking noise on my 03 Yukon XL, but it is so random and intermittedly that I can't recreate it when I want to and hard to diagnose. It is when driving (not stopping or starting), and does not occur on every trip, but about every 3 or 4th drive.

      AFM Disabler Question

      By KARNUT · Posted

      I’m doing an experiment on a vehicle I don’t have much money in. I’m going by the premise that after they last 100K miles they were no mechanical problems with assembly. Or defects with the parts. With oil changes by the minder for the first 127K miles when I acquired it. I quickly went through low mileage oil changes then settled on 5k oil changes with close to 170K miles on the vehicle currently. I did have the option to turn off the cylinder deactivation. I didn’t on this vehicle because it’s in ECONOMY mode at least half the time. It should be a no brainer frequent oil changes are the key. The manufacturer gets away with the long oil changes with its severe service  maintenance. Just ask them what is normal.

      Hot air constantly blowing through floor vents, drivers side only?

      By baglie1 · Posted

      Even set to "recirculated", the air pushes out and is hot. I have noticed that sometime it doesn't want to switch between recirculated/vented air. Say it is set to Circulated Air and I want to switch to Vented, when I click the Vented button, it just quickly lights up/clicks and immediatly switches back to Circulated. It's done this a few times now. So maybe it is an actuator getting stuck? But then, that doesn't explain the hot air when everything is off does it?

      I wonder what the price is out at the coast, Big Sur or other out of the way locations as I bet they are charging quite a premium over the in land pumps.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Were you looking at the HD trucks on the GM website or the half tons as that makes all the difference. As far as I know there are only two options for the HD trucks and that is the standard 2 speed transfer case or the 2 speed transfer case that has the added 4 high auto feature and they put that transfer case by default into the LTZ and High Country although its optional in the LT and not sure if its available in the work trucks.    The half tons, that is where its been a total mess in my estimation for a few years now with most trucks below the top trim having the single speed transfer case as standard but with the option of having the two speed such as one would get by choosing the Z71 package, however then not being able to get the two speed transfer case with the towing package unless it was a higher trim truck AND had the 6.2 gas so one could combine the towing package gearing diffs with the two speed transfer case. Having said that if its a trail boss package then it gets the two speed transfer case but not necessarily able to get the tow package as it would depend on trim level and engine chosen. Believe me, people have bought the GM half tons assuming "of course it will have a two speed transfer case" only to find out after when they really pay attention to what they now own .... crap, there is NO low range !.    I don't believe Ford or Ram have gone that way yet with their half tons but like I say its been a few years now that GM has done this with the half tons.
