The signal for tbe cruise on a GMC is on the brake pedal it's a separate circuit from the actual brake lights! You...

    Flasher for LED’s without using a Resistor?

    Its the load on the electrical system I'm trying to save I know it's not that much but alternators do wear out faster from the loads put on them, maybe not the mechanical part but the regulator and such why not benefit from this as much as possible? Also say I break down somewhere and need to...

    They should be the 3.73 from the yard I’m getting it from if not I will find out when I put it in 4WD I could count the turns of the axle vs the pinion to double check once I figure out the math

    Rear Differential issue Rebuild or Swap W Boneyard rear?

    I changed my mind and I’m getting a junkyard rear I will keep the old one to fix it probably do a total rebuild and change the carrier to something more durable I like the way the G80 works but your right it’s a weak link. The Yukon has 278000 miles on it so it was bound to fail

    No it's constant regardless of speed it's just faster as I go faster, and only in drive no sound in reverse? So I'm not 100% till the cover comes off what it is

    Rear Differential issue Rebuild or Swap W Boneyard rear?

    I just found a guy parting out a 01 Denali he wants $300 for the whole rear axle! He’s checking the ratio and if it’s the same in the morning! You think $300 is a good price? I don’t know if the Denali has the same rear as the Yukon’s? It has a 6.0 in it so it may have a different rear since my...

    Flasher for LED’s without using a Resistor?

    Is there a Flasher that will work with LED bulbs without the use of a Resistor? I have been looking for a Electronic flasher that will work in My 01 Yukon my only reason is because the use of a Resistor kinda defeats the purpose of the led pulling less power! The only benefit is the life span of...

    Rear Differential issue Rebuild or Swap W Boneyard rear?

    It was full when I changed the oil and there’s no leaks I think the previous owner was towing really heavy trailers because the rear tires were almost worn out and the fronts had 75% + tread left they put all 4 on at the same time! The invoice was in the glove box when I got it! It might not be...

    Rear Differential issue Rebuild or Swap W Boneyard rear?

    The front has been cleared! Nothing wrong up there! I had it up on jackstands in 2WD and the noise is definitely in the rear! Now the exact source has yet to be determined? I did change the fluids front and rear a couple months ago and I didn’t find anything unusual in it, you can definitely...

    Noise steering drag? Front differential? Auto 4WD

    Turns out it’s not the front differential it’s coming from the rear I verified it might be the pinion or the locking mechanism working on a solution now

    Noise steering drag? Front differential? Auto 4WD

    It’s only a 1/2 ton and 150lbs is what the Mitchell guide says I checked several sources and they all say 150 for this year and model. And your running a diesel they have completely different suspensions yours is a lot heavier to handle the weight of that engine and all the extra torque. If you...

    Noise steering drag? Front differential? Auto 4WD

    That’s what I’m thinking but I’m just afraid it may not be true I don’t want a wheel flying off because the hub fell apart! I have 2 unused hubs and looked at them closely they are pretty solid but without definitive proof they don’t need the support of the spline, I know the shaft is supposed...

    Noise steering drag? Front differential? Auto 4WD

    I will have to check it closer I hope the bearing race isn’t seized into the differential if it’s getting hot enough to burn the oil. If it is the differential housing may be scrap? I’m going to look at it this weekend if the rain stops.

    Noise steering drag? Front differential? Auto 4WD

    Do you think a bad output bearing was bad do you think it could cause a intermittent drag? I also noticed a Burnt oil smell after driving a while I thought was a leak from the engine somewhere but I think it’s coming from the differential! So it could be the bearing as you said
