    P0608/Cluster Issues

    I have a 2WD 02 GMC Yukon with 5.3/4l60e. I replaced with a new VSS, 2 months ago. I installed a new cluster in my truck a few months back. I am getting a P0608 code relating to the VSS Output Signal. I have no speedometer on the cluster but every other gauge works, I can read my speed through a...

    2003 6.0 yukon - weird idle after knock sensor replacement

    Did you replace the Intake Manifold Gaskets? Did you use genuine GM knock sensors and replace the harness too? Did you torque the knock sensors? Did you build a RTV dam around the grommets? Did you make sure that your PCV valve was put on and clamped? Did you hook your vacuum hose that goes from...

    No speedometer, front windows, heated seats, locks.

    Check if you’re getting speed when hooked to a OBD-II scanner and driving.

    Longtube header preferences?

    Here is the video of how my exhaust setup sounds.

    2005 Tahoe 4WD - Help! Bad Shake from 0-45 mph

    Can you post a video of you moving your front end parts too? It would be helpful to see what else is messed up.

    Longtube header preferences?

    I just rebuilt the 5.3 in my 02 Yukon SLT and went with Speed Engineering 1 3/4” Longtubes to Off-Road Y-Pipe to Black Widow Venom 250 to 3” pipe and dumped over the rear axle. I paid $460 for both long tubes and y-pipe. Fitment was good too. I’ll get you a video tomorrow so you can hear/see it.

    Steering box

    Sorry for the late response. I don’t think the tube matters as much as getting the bolts torqued down (106-in lbs) and using the correct O-ring on the tube.

    Steering box

    That steering box is soaked. Try to get someone in the cab turning the wheels while you video the box itself from good angles and see if you can spot a leak.

    Rebuilding the 5.3 in my 02 Yukon! Need advice/tips!

    Hahaha I haven't got the exhaust finished on it yet. It's just running out the catless y-pipe currently. I haven't touched the tranny at all yet, I see myself having to do that next for sure. I ended up going with a Truck Norris Cam and it works great. I'm still watching videos on HPTuners to...

    Rebuilding the 5.3 in my 02 Yukon! Need advice/tips!

    So I took some pictures of everything for ya and I'll try to explain this in the least autistic way possible. I originally was going to run an LS3 throttle body and an X-Link to accomplish the 90mm TB & GMT900/TBSS intake swap. BUT, the problem is the 99-02 and 03-07 vehicles DBW TB's are...

    Steering box

    1) Have you checked power steering fluid level? 2) Have you checked for leaks where the power steering cooler connects to the steering box? 3) Have you checked the metal barbs that come out of the top/back of the steering box, they have an o-ring too? 4) Have you checked your intermediate...

    Rebuilding the 5.3 in my 02 Yukon! Need advice/tips!

    Another update boys, I got my intake hose hooked up and O2 Sensors in. I got my hands on a MPVI2 and was able to change some things around to be able to get the Yukon running half way decent. This is all brand new to me but using HPTuners hasn't been rocket science by no means. I also managed...

    Rebuilding the 5.3 in my 02 Yukon! Need advice/tips!

    I finally got my throttle body hooked up. I had a hard time finding any information on this. For anyone that sees this in the future, if you have an early 00-02 DBW truck/SUV. You DON’T need an X-Link or LS3 TB, use the LS2 DBW TB and an adapter. It’s way cheaper and achieves the same thing...

    Rebuilding the 5.3 in my 02 Yukon! Need advice/tips!

    I need some help boys. I just got mostly everything back together minus the MAF sensor, intake tube, and X-Link to run the LS3 TB. When I try to crank it up, it acts like it wants to fire but no luck. I checked spark on both sides and it’s good, tested fuel pressure at the rail and it’s 58 psi...

    I’m finishing up buttoning up some odds on the block and waiting on my long tube headers to get here. I should have the motor in the truck here soon!

    Rebuilding the 5.3 in my 02 Yukon! Need advice/tips!

    I finally got a pair of the updated valve covers, new sensors all around, and even a harmonic balancer. I am also currently rebuilding the front end suspension, and repairing the A/C and heat in the Yukon.

    Here is yet another update, I finally got around to putting the rotating assembly and cam together. Next up is the timing set, just waiting on a tool to get the crank timing sprocket off.

    Thank you for the advice! I actually decided against doing the valves and just doing springs/seals/and CHE trunnions.

    Rebuilding the 5.3 in my 02 Yukon! Need advice/tips!

    Oh yeah. The assembly is definitely going to be a blast! I actually just got my torque wrenches calibrated, bought a speedway adjustable ring compressor, valve spring compressor, feeler gauges, and some plasti-gauge. I'm still in the process of buying other misc. things while the engine is still...
