    Odd hum/whine from rear while accelerating

    The sound is most noticeable taking off from a stop up to about 40mph. It's subtle, but the pitch and frequency change with increased RPM/speed. If I'm just cruising or at freeway speed I don't really notice it. Sounds like it's coming from the rear end/driveline area. Trans seems to shift...

    Trans temp on new cluster

    I just installed my new/reconditioned cluster from fixmygauges.com. Overall I'm very happy with it. I'm excited to have a trans temp gauge on the dash since I tow frequently. I used the torque app to monitor my trans temps via the OBDII connection vs. the analog trans temp gauge. I found the...

    Intermittent battery drain - '06

    Found my battery dead down to 4v after parking for a few days. I don't drive the truck a lot so it sits for a week or more a lot, but hasn't been an issue until recently. First thing I did was change the battery. Now working with a fresh battery it happened again. I'm getting 1.1v current...

    Best place for cluster rebuild

    I'm having issues with current draw killing my battery and my cluster is suspect. I'm just going to go ahead and send it in for repair/rework since I have at least one light out and I'd like to see about adding a trans temp gauge. Who does the best work? My coworker used an person on eBay...

    NNBS brake job done - pedal not firm

    Finally did a full brake job (front and rear) with new calipers, rotors, pads, and stainless braided hoses (all six). The fronts got changed to the larger 07+ calipers/rotors. I bled the entire system refilling with fresh fluid. Test driving does not feel firm like I was expecting. I'm thinking...

    Are JL4 calipers needed?

    I'm getting ready to buy calipers for front and rear brake job. I will be upgrading the front's to NNBS calipers/rotors. I have stabilitrak/active braking and I see listings for JL4 (active braking), do I need to use those calipers or can I use any listed for that model year?

    Rear center brake hose replacement/installation

    I'm getting ready to install the 6 hose Goodridge stainless braided brake hose kit. The caliper lines will be easy. I'm concerned about the 2 rear center hoses above the diff/frame. I know the spare tire will need to be removed to get access. Are there any special tools needed to replace...

    Help choosing stainless brake line kit

    I want to upgrade to stainless braided lines when I do a brake job soon. Which is the best kit for a 2006 LS with stabilitrak (Russell, Stoptech, Centric, Goodridge, etc.)? I've read some kits don't include all the hoses for the rear (5 instead of 6) and others report them not fitting correctly.

    Service Brake System DIC message

    I replaced my original parking brake pads yesterday. After restarting the parking brake light comes on and the DIC message says "service brake system / stability disabled". I did slightly push the caliper pistons back in with a clamp to make re-installation easier, but I'm not sure if that...

    Roof cargo rack

    I want to put one on my rig mostly for camping when we travel with lots of gear. Any recommendations? I'd like something that replaces the factory racks, but will also consider a bolt on. I want aesthetics and function. Post pics if you have them. Thanks!

    Rear hatch fail

    The rear hatch will not unlock or open on my Tahoe. Both the glass and the main door latch. Using either the key FOB or the door locks will not unlock it. All other doors lock/unlock just fine. I checked several fuses and relays and didn't find anything there. Is there something else I can...

    Lubelocker gaskets

    I wish I would have known about these gaskets the last couple times since I've dealt with minor leaks even after being very careful in the past. Scraping old gaskets and RTV off takes the most time. The lubelocker gaskets require no RTV. So far no leaks with the new gasket, but the real test...

    Oversize spare

    Finally sorted out my spare situation and was able to stuff a 285/70-17 underneath. I really wanted a full size spare since I had been carrying the original 265/70-16 and thankfully did not need to use it. Mostly sharing just to help others who might be in the same situation. Sent from my...

    Front diff capacity?

    How many quarts will I need? I'm probably going to mail order and don't want to get stuck with a full bottle on the shelf. Thanks!

    Bilstein shock swap - installation questions

    I'm considering swapping over to Bilstein shocks and getting rid of my Rancho 9000's. I'm all over the place with the Ranchos and just don't care for the ride. I haven't replaced shocks myself on this truck and I'm wondering the level of difficulty to do it myself? I know the rears are...

    Rear diff covers

    I'm going to be servicing my rear diff and figured I might swap to a different/aftermarket cover. I want something with a drain hole for sure. Anyone have any recommendations? Something that comes with gasket and bolt kit? Or just a good bolt kit recommendation too? Thanks!

    Wheel stud replacement help

    Well the tire shop broke a stud while rotating my tires yesterday. Rather than take it to another shop I'm just going to fix myself. I've done it on another vehicle before so I know the basics. This is on the rear wheel so I'm looking for any tips or a link to a good video specific to our...

    Torque Pro - no trans temp?

    I got the Torque app up and running today. It connects fine and I can see various real time readouts, however the one I really wanted was trans temp. When I add it from the list it doesn't have any data. What am I doing wrong? Does my model Tahoe not have the ability to read trans temp? Any...

    Torque App

    I'd like to start a discussion to learn more about this app. I want it primarily for the transmission temp gauge. It would be a good interim solution for me while I'm towing until I can upgrade my cluster someday. Besides the paid version of the app what else do I need to make it work? OBD...

    Throttle body cleaning

    I've done quite a bit of searching and watched a few videos, but haven't seen too much info related to our specific engines. It's pretty straight forward stuff, but I'm wondering if anyone has any tips? Should I remove the throttle body or is cleaning still attached ok? What about the IAC...

    Seat creak

    I've had a pretty nasty sounding seat creak from the passenger seat for some time now. You can hear it when taking off from being stopped or breaking/accelerating. Anyone know what usually causes this and the fix? Hoping it might be as simple as tightening a few bolts? Thanks!

    Coolant change question?

    Gearing up to change coolant soon. Book says the system holds 16.7 quarts (roughly 4 gallons). I plan to drain the radiator using the drain petcock then refill with distilled water, cycle system, drain again, repeat until clear/water only, then refill with straight dexcool.

    Upgrading ignition coils worth it?

    It's time to do plugs and wires and I'm also considering upgrading to a set of MSD Blaster ignition coils. They aren't cheap though ($381 for the set)! Any thoughts on this? Are stock coils good enough, will I notice a performance improvement, mileage, etc? Thanks!

    Ignition tune-up time

    I'm getting close to the 100k mark which is the manufacturer recommended interval for spark plug replacement. Anyone have recommendations on plugs and wires other than Delco? I know the wires are probably fine, but I like to upgrade things even if it's just marginal. I've read MSD is ok for...
