Chevrolet - Blazer :: 2002 - Wheel Drive Clunk Disengaging?
Jan 16, 2012
I own a 2002 Chev. small blazer with 4 wheel drive available. Largest V-6 available. There is a clunk sound I can hear and feel as this vehicle is shifting OUT of 4 wheel into 2 wheel drive. Going from 2 to 4 wheel drive is perfect. First mechanic (test drove alone) said he would have to tear apart the front transfer case to determine fault. 2nd mechanic (with me along) did power brake slow turns in parking lot. Said the electric shifter was bad and would have to tear apart the transfer case also. Neither mechanic put the vehicle up on a hoist.

2002 Chev trailblazer, I have had the throttle body cleaned.... Sometimes after short stops, my vehicle will not crank, some times I have to step on the gas several times and it will finally crank, it sets no codes, no check engine lights come on. If it sits overnight, or for more than 20 minutes it cranks right up.

A co-worker has an issue with a 2002 Chevy Blazer where the oil is mixed with the coolant. My understanding is the usual causes of this are blown head gasket, cracked cylinder head, or cracked engine block. If the cause is a head gasket, they'll probably fix it. Cracked cylinder head makes fixing it iffy. A cracked engine block probably means junking the vehicle. Is there a fairly inexpensive way of determining the cause?

Immediately after I had four new tires installed on a 2000 Blazer 4wd, the front wheel bearings started making noise. At the time I thought the noise was from the new tires. A few thousand miles later my mechanic told me I needed two reman hub assemblies (sealed bearings) for ~$350 apiece plus labor.
Is there anything that the tire shop (independent not chain) could have done (accidentally or otherwise) to damage the bearings during the tire installation? I have to get 4 tires for my 93 Chevrolet Caprice and don't wish to repeat the experience.
Whoops, forgot to mention this happened at 56k miles when the truck was five years old. Is it possible that the bearings were borderline and the process of mounting the wheels put them over the edge? For instance, someone being a little over enthusiastic with an impact wrench.

I have an 02' Blazer 2Door 2WD 4.3L vortec. Great truck - very low miles. About a month ago the fuel pump went out. She was showing signs / not starting on the 1st/2nd try and finally wouldn't start. It's a 12 year old pump and I was also that guy trying to make til Friday on a quarter tank - so no complaints so far. I checked the relay and fuse, all good there - so I bought a new AC Delco and fuel filter. Drained and dropped the tank, cleaned and dried the tank and installed the new fuel filter. The pump came with a new pigtail - so I wired in the new pigtail, attached the hoses and re-attached the tank. Not bad for 6 hours of work ( first time - don't judge ). She fired right up and ran like a champ / about a week later I stopped and filled up the gas tank. Next day - no start / no whine from pump / 0 psi at the schrader valve.
Assuming it must be an electrical issue - I dropped the tank and tested the gray power wire / 12 volts. But to be thorough / in case I made a mistake / I stripped and re crimped all the connections, heat-sealed the sleeves and wrapped in all in electric tape. Tested the pump - she hummed like a kitty. Re-installed the tank and she fired up like a champ. Drove around a couple of days - stopped and filled the tank with gas. Same thing - wouldn't start right there at the pump. i poured fuel in the intake - she would start and run until the fuel burned up.
No hum from the pump. had it towed home ... again ... began to siphon my now full tank of fuel to drop it yet again. At about 1/2 way , I tried her and the pump primed and she started right away. For the past two weeks I have been unable to make it NOT WORK - but i am worried to go very far , less i be stranded again. on the gauge I get 60 with the key on and 56 running. With the engine off the pressure holds for quite a long time - well over an hour+. So what would cause a brand new AC Delco pump to not work only when the tank is full - then start working when some of the fuel is removed?

What are the symptoms of a worn motor or transmission mount? I feel a distinct clunk when I place the car in Drive or Reverse from idle. I did not notice any problem when I bought the car few weeks ago. Before spending 300+ I checked for the problem one more time. The problem is that the clunk was all but gone. An intermittent clunk! What gives? The car is an '05 Malibu w/4cyl, 119k. The former owner had the transmission fluid changed at 94k.

I have had a 2000 Chevy Cavalier 2.2 liter 4 cyl Automatic for about 5 or 6 years now. I have noticed the whole time I have owned it that when I start the car and shift from Park to Drive I hear a clunk and the with the hood open the engine pivots back and forth one time more than it is supposed to. This only happens from park to drive, it does not do this from park to any other gears, and once the car is in drive everything is normal. The car has no shifting problems at all, no slips or clunking while driving or hitting the gas real fast on take off.
I changed the all three mounts on the car yesterday. Upper engine mount (still in decent shape), lower dogbone (tore to hell), and Transmission mount (decent). I really haven't noticed it get any worse over the years I just know its not right. I have never changed the fluid or the filter since I owned the car, and most likely it has never been changed in the cars life. Could a dirty filter, and dirty fluid cause this problem? Or could the linkage need adjusted or replaced?

I just noticed the 4 wheel drive on my 2000 Chevy S10 doesn't seem to be engaging. The traction doesn't get any better turning it on and the other day I got stuck on a hill and the back wheels weren't spinning. What I can check or look at to fix it?

Chevrolet Tahoe 2007
This service light came on 2 weeks ago. The next day, the car seemed to be trying to switch from 2 wheel to 4 wheel drive. Took it to the dealer who found nothing. We drove the car for 2 days without any service lights coming on. Then the switching ( 2 to 4 WD) started again, but this time the transmission would not go above 1st gear. Pulled over and turned off the engine, then tried to restart it. Nothing. Dead. A few minutes later, we go it back home. Had CAA tow it back to the dealer. It's been a week and they found nothing. They are looking for engine codes that would explain the problem.
Is this an electrical problem or a sensor issue?

My '05 F150 (92,000 mi) 4 wheel seems like it is engaging and disengaging when activated. Makes a clunking sound on light acceleration then quits when I back off the gas. Not sure if it is engaged then or not. I noticed this on a gravel road when I had turned 4x4 on to distribute oil around the system since I had not used it in a while. What it might be and if it is any easy fix or a trip to the shop.

What are symptons of a "bad" drive shaft? Just curious because during a recent trip to the dealership for an oil change a mechanic told me I had one(I had mentioned I heard a noise that seemed to speed up and slow down as I drove-kind of a whirring noise). He arrived at that diagnosis by pushing down on the hood with enough force to make the vehicle(2002 Chevy Trail Blazer w/4wd) bounce up and down - there was a clunking noise. I haven't taken it in to have it looked at more closely, mainly because I am afraid of the cost. What's involved in replacing a drive shaft? What's the cost? If it is really "bad" will it break suddenly and cause an accident?

Every day I make a u-turn around the median in order to get to our driveway...which means I turn the steering wheel all the way to the left. As I turn the wheel and drive, there is a clannnngKK sound on the driver's side from somewhere near the front. I wondered if there is something getting hung up/caught "under there" but have no real working knowledge (obviously) of my truck's anatomy. It only makes this noise when I make this u turn. I've not heard it any other time.

I have a 2002 Camry, and recently on the passenger side towards the front wheel there has been a fairly persistent thump or clunk when I brake at low speeds (i.e. immediately before a full stop). I took it to my local mechanic yesterday to see if he could figure it out, and unfortunately he wasn't, although he did point out that my dog bone was cracked and suggested changing that out. Afterwards, the thump/clunk did seem to be more subdued, but it's still obviously there.

I have a 2002 chevy Trailblazer that when you put it into drive there is a vibration.It does not do this in park or neutral. I have checked the engine mounts and transmission mount, and they look good. The vehicle has a little over 118,000 miles on it and the engine runs and drives great except for this vibration that i do not know where it id coming from. What may be my problem?

I have a 2002 Avalanche 2500 4w drive with the 8.1L engine. The problem is that it is leaking oil, but only after a long drive. Plus the leak happens like a spray after the car has been sitting for more than 20 minutes. The oil is leaking from IN FRONT of the driver's side front tire and I can't see any oil up on the car. The oil leak only leaks for a short time and then stops until the next long drive. The truck has 118,000 miles.

Our 2007 Chevy Tahoe 4 X 4 recently displayed a "Service Four Wheel Drive" panel light a couple of days ago (upon ignition on a sunny, dry day). The light had been steady which, when we read the owners manual, indicates a problem but no immediate service required. One of the possible solutions was to remove and close the gas cap in case it had been incorrectly closed during the last gas-up. That did not work. Yesterday, during a snow storm, I tried using the 4WD. The dial would move to the different settings, but no 4WD activated and no light illuminated indicating which gear it was in (2WD, Auto, 4H, 4L). We checked the fuse for the 4WD but it is OK.

I have a 02 F250 4x4 5.4. As I drive and when pulling into a driveway I hear a clunk that can be felt in the floor and the steering wheel. I've replaced the wheel bearings and seals, shocks, ball joints, sway bar links and bushings, tie rod ends at the gear box and "right hand inner". The other two tie rods are tight and so is the track bar. I cannot duplicate the sound if I jack it up and move parts around with a pry bar. I can however move the steer box sector shaft upwards about an 1/8. I've adjusted the screw but it didn't do anything. Could it be the steer box or the springs? I've even mounted a GoPro underneath but everything moves and I can't tell why it is.

Yesterday I noticed when I pushed the 4x4 high and the 4x4 low button nothing happened, there was no light indicator coming on at the dash, and also there was no differece in gears when 4x4 low was selected, is there an easy fix to this like possible a fuse blown?
