#110 of 119 knocking at speeds between 10 and 15 mph
Oct 12, 2012 (7:21 am)
I had the misfortune of losing my old (favorite) truck to a head on collision. Lacking funds and only getting what we could out of the insurance company we had to settle for a vehicle about the same age as my truck. With that said, we bought a used 2002 GMC Yukon Xl, 5.3L, 2wd truck. We have had the vehicle about 6 months now and the truck has developed a knocking noise at very low speeds when the engine and drive train are not tensioned. Basically the noise happens if you were ghost riding your truck thru a parking lot. As soon as negative tension or positive tension is applied to the drive train the knocking noise goes away (when power is applied to speed up or breaks applied to slow down). I have read all about 4wd versions adn front end issues with steering shafts etc but I dont have a transfer case or front end half shafts and CV joints to worry about. My dad thought it might be the universal joints on the drive shaft but I figured if they were going out you would be able to manually jog the shaft when it is parked and either visually or thru touch, feel any slop in the joints. My initial thought before I crawled under the truck was a drive shaft carrier bearing wearing out but the drive shafts dont have carrier bearings so without pulling the entire drive train apart I am struglling to diagnose. Was wondering if anyone else out there was having similar knocking sounds with a 2nd generation Yukon XL (00-06) that isnt 4wd??

#112 of 119 Clunking sound from Rear Left

2000 Yukon XL. I had my BIL change my struts and ever since, I've had a strange clunking sound near the rear left. It sounds like the spare tire is swinging back there but the tire is well secured. I've removed the jack and tools from the jack compartment to be sure it isn't them and the noise continues. Any rough road that makes the truck rock a little, sets it off. We noticed when we were loaded down that the noise vanished, but even though we loaded down today, the clunking is worse than ever. Ideas on how to isolate?
#113 of 119 FAST REPEATING SOLENOID??
Jan 11, 2013 (10:19 am)
I have a Yukon XL with about 138,000. I bought it at 129,000
DID the Transmission 5,000 ago.
Anyway I keep hearing this sound and it's driving me crazy. I am pretty mechanically inclined.
nor me of my friends can figure what it is on test drives when it happens.
I can best describe the sounds as a fast repeating clicking / thumping / sometimes skweeking . it will repeat the clicks about 5 times. really fast.
Sometimes when I am driving it sounds faintly like I am going over the dot reflectors on the highway at about 55MPH. When I am going slow with the window down. sometimes I hear a skweaking componet to it that sounds like a seagull
I am convinced this is electronic and not bushings / chassis.
It does not seem to affecting the drivetrain or handeling when it happens. and it completey random. or at least I have not put a pattern to it yet.
The last time it happened was yesterday. I was doing about 35mph and hit the brake to slowdown for a lefthand turn. while under braking I got the 5 repeated sounds.
note this doesn't always happen during braking. most time time just while driving.
I welcome anysuggestions.

And Any ideas on where to find Denali parts for cheap online? guys ? Thanks!

Sounds like a ball joint or steering linkage issue. Is it 4WD or 2WD? Doesn't sound like a CV Joint problem but if 4WD it might be just that. Is it one pop or a loud clicking noise

Its an AWD Denali and its one loud pop as I turn into a parking place. When the wheel is turned all the way or close to being all the way it will pop almost everytime as I ease it into the parking spot.
Its not a clicking noise like when the CV boot tears and loses the grease.
Thanks for the ideas!

Could be in your ride control. I am having an issue that rears it's head after driving for an hr or so. A very loud thumping coming from the left rear. You can feel it through the floorboard and hear it outside quite loudly. It is not affected by road conditions nor braking. I am leaning towards rear axle bearing, but have never heard one thump before. Nothing is loose anywhere, and is so loud it sounds unsafe. But comes and goes, normally after 100 miles or so. Any ideas?

I found and correct my Issue So I just wanted to share it with everyone. my issue was fast repeating metailic bangs that when faster at speed. at 60 miles an hour it sounded like a 3 round or 5 round burst from a full auto ak-47.
So the culprit was the rear drum shoe. the rear shoe is shaped like a horse shoe and is one peice. it broke and was intermittenly getting caught on something. it was transfering energy into it and was acting like a spring due to its shape.
hope this helps someone

Good sleuthing. Seems like an odd part to break though. Casting defect perhaps?
