#82 of 119 Yukon Making Popping Sounds from Rear of Vehicle
Jan 04, 2010 (10:53 am)
I have a 2004 GMC Denali AWD with 6.0 liter. It has about 82,000 miles on it. I replaced the rear pad about 10K ago. I have it serviced regularly (oil/lube) but have not had the 60K or 70K (whatever it is) service done.
The weather here in Atlanta just got real cold...in the teens and 20s. While driving yesterday, I just started hearing a popping sound coming from the rear of my 04 Denali. After a long drive, I parked and came out of a store....started to go and it seemed hesitant to roll almost like a flat tire but pulsed...smooth, resistance, smooth, resistance, etc. Got out, inspected all 4 wheels, got back in and it didnít happen again. Then experienced some pretty good vibration while driving too for a minute or so but that has not happened since. Now it just pops from the rear of the vehicle. At first, I was thinking the automatic leveling system but now am thinking a rear u-joint?
Thoughts or same experiences?

I have a 2007 Yukon and the noise your hearing from what i've been told is the self leveling feature your Yukon has.
#84 of 119 2004 Yukon - clacking and white smoke
Apr 26, 2010 (9:07 am)
My Yukon has 90k miles and has recently started clacking and smoking upon start-up. The anti-freeze level is also low and there is a gurgling sound when turning and at quick start/stops. I had the water pump replaced but there is still loss of anti-freeze. My mechanic couldn't find anything related to the noise and smoke so suggested a high mileage oil change - done. The problem disappeared for a couple weeks and has now returned. It seem to clatter and smoke most after an extended ride (100+ mile), although has done it with local rides too. Was thinking maybe a small leak in the head gasket and considering a product called "Thermogasket" to seal any leaks.......any thoughts or advice would really be appreciated!!
#85 of 119 Tired of GMC

I have a 2005 Yukon 4wd. In the past 4 weeks, I have had the transfer case sensor and the speed sensor replaced, so it now knows what drive mode it's in and stays out of limp home mode. Now it makes 2 different noises. The first and most annoying is a constant metallic rattling/grinding that starts as soon as it starts rolling. The other is a whining that changes pitch with vehicle speed. Neither of these noises are affected by engine RPM, just by the rolling of the car. The first noise seems to come from the right mid-rear of the car. The other I can't tell. It just ticked over 100k on the odometer. Can't find anything loose underneath. Any ideas?
#86 of 119 Probably 2 things
Jul 28, 2010 (6:49 am)
Kind of suspect you have 2 other seperate issues going on. Pull the right rear wheel and check whether the brake caliper has frozen on 1 side. If the inner & outer pads are not wearing evenly, that is the first problem. The driveline whining is more difficult to trace, but I would first check the u-joints, then possibly the front hub bearings. I've had both of these things happen on mine with similar symptoms. Another possibilty exists that the brake pad wear indicators (stainless steel shims between the pads & the caliper) are touching the rotor due to excessive pad wear on the right rear.

Have you checked to see if you have a loose heat shield or a bad baffle in your muffler?
#88 of 119 '01 Yukon Plugged converters?
Nov 29, 2010 (2:00 pm)
I thought the wifes truck was about to throw a rod, but when I put it up on the stands and got under it to listen, the noise was coming from inside the converter on the left side and at the spot where the two pipes join.It sounds like a bunch of chain bouncing around inside the pipes! I think the cat has come apart on the inside and the pieces have now plugged up the wye connection as I cannot get up over 2000rpms.Looks like I'm gonna have to earn my keep and go pull that pipe! I'll let ya know what I find!
#89 of 119 2005 GMC Yukon whirring/rubbing noise on driver front side
Dec 20, 2010 (9:44 am)
We just bought this truck last month. During the time we've had it, it has developed a whirring or a grinding noise on the front driver side. Took it to Les Schwab to have it checked thinking that it was the bearing going out. They said everything was sound. Took it home and put it up in the air in our own garage and pulled it apart and again bearing was great. put it together and went for a drive and it still makes the sound. you can feel it in the floor when your driving. Im out of ideas. anybody got a take on whats going on with my 2005 GMC Yukon?

Sure enough the left side converter had come apart on the inside and plugged things up. So to expedite her getting back on the road, I used...get this...a toilet auger on a drill motor and cleared out the converters on both sides. I will have them both replaced after the first of the year, after things get back to normal around here. The truck runs great and smells like one of my old cars from high school!

I apologize for your experience. If you are unhappy with the dealer diagnosis I would definitely recommend taking your vehicle to a different dealer for a second opinion. You may even as a technician to go for a ride with you. Please keep me updated on your progress.
