Has anyone put the 7.5" rough country lift on an 08 sierra 1500 yet. I have and I am having some problems with braking. Looking for answers.

what size wheels and tires did you put on there. what kind of breaking issues are you having? not stopping good? vibrating bad when you hit brake pedal?

Bad vibration when I hit brakes. For some reason my stablitrak is off and I think it has something to do with that. I have 35's with 18" wheels. Not sure why I lost my stabilitrak.

If you're running aftermarket wheels, they are probably interfering with the clips that are on the rear studs. They are there to hold the drums together during assembly, but are not necessary once assembled. If you haven't removed those, give it a shot, and I'll bet the vibration goes away.

 

Can't help with the stabilitrak issues though.

yah what he said.. I had the same problem, it was just the tiny insignificant clips on the rear drum. Its incredible how much vibration those little things can produce. Take them off and you will be fine. I duno about the stabilitrak, but your vibrations will go away.

Double check all of your ABS sensor wires that were disconected during dissassembly, if they are not all clean and conected tightly, it could be shutting down stabilitrac. Hope this helps.

Nice...any stabilitrak issues usually come from a ABS sensor wire/connection. Did you do the install? If not, take it back to the place that did and have them fix it. More then likely, they or you pinched/cut/didn't connect something back up. I know when I was installing mine, I came close to breaking them.

Lets just say that the CV Spacers are made of a plastic/composite type material. The kit is also not a full-drop kit, so your CV angles won't be the greatest. If you have a 2WD, then the kit is decent.

That would be a great kit for your set-up. 33's are perfect on it too. Someone also has a kit that can make the 5" go up to the 7.5" for cheap. If you ever want to go higher down the road, the option is there.

This might seem like the super obvious answer to your StabiliTrac issue...but you don't have the button turned OFF do you!? Like I said...might be a stupid comment...but then again sometimes the obvious are not always THAT obvious!

 

I have the Denali model and there is a "traction" button on the lower cluster of buttons below the thermostat controls that if pushed once turns off the Stabilitrac and if held for 5 seconds turns off the AutoRide too. If it were to get "bumped" and you don't notice the tiny yellow indicator light...that may be your issue!? Then again...not sure if the Sierra's have the same button as the Sierra Denali's!?

We have the same button, well I guess it might depend on your interior package. As far as I know, it all turns back on with each cycle of the ignition.

      Some Assembly is Required

      By Grumpy Bear · Posted

      Missing pieces of the Assembly   Detergency vs Solvency   Not the same thing. Detergency is the mechanism that surrounds solid particulates preventing amalgamation. Usually accompanied by a Dispersant whose job it is to keep those encapsulated particles in Suspension. Solvency keeps things that can be dissolved in solution.    Salt is a solid that can be dissolved. Pepper is a solid that cannot be dissolved. A detergent/dispersant is effective on pepper but a solvent is more effective on salt. As long as the solids remain in either state, dissolved or dispersed then they can be be removed with the oil upon change.    How many wranglers does it take to herd cats? Depends on how many cats your herding. How much sponge does it take to soak up water? How much water is there to soak up? Point is most oil blends start with some herding ability and next to zero sponge and recently even fewer wranglers are being sent to do the same job.    So you start with a dozen cowboys and zero cows but at the drive progresses you pick up cows along the way, but not cowboys. At some point you have more cows that the wranglers can handle and some leave the herd. Deposits. And the API has an acceptable number of cows they are willing to let loose. In the ideal world zero is the right number for he rancher but to the butcher....a few lost is fine. This cow is beat to death. Let's move on....   Solvency isn't something oils on the Walmart shelf care about AT ALL. Problem is, you motor does. Fuels driven varnish sticks rings and only a solvent can keep them in check. The bet is that the solids driven portion that plug the expander rings and the oil drain backs and VVT screens and AFM screens will be an issue long before varnish is. Not that it wont be but if they market well enough the consumer can be kept ignorant enough to either believe it is "normal" (A quart in 1 or 2K is normal) OR is kept at bay longer than the first owner is likely to hang on to the unit. Solvency cost money.    Now the OEM's have John Q. Public buffaloed into the belief that the number cows accumulated along the trail is a known and predictable CONSTANT. It isn't. Nor is the rate at which they crossed paths with them. Only the number of wrangles is constant. Or was. Each new generation of oil sees fewer and fewer of them.    So what happens when the number of cowboys is lower (lower TBN) with each seasons trail but the trial is longer (OCI) and the number of cows along that trail continues increase? (Conditions that promote deposits).    For awhile the blenders were on to something. Better bases are harder to degrade (fewer cows) but that was overtaken by a longer trail (OCI) and improved breeding (More cows) while continuing to reduce the cowboy staffing levels (TBN/Aniline #).    Marketing has been successful. We've fired most of the staff, cows breed line bunnies, the trail is ten times longer and we've convinced the boss his ranch is in better shape that it ever was.    That kids is just the cleaning side. The side few pay attention to.

      Looking for this part for my truck. They don't sell just that one piece and to get it you have to pay over $100 even used for the whole air tube. The piece the hose clamp snaps into that is held on by the screw and nut. If anyone has access to one please let me know.
