Question about 2006 Hummer H3

1 Answer

Loud clicking sound from beneath my H3

Hard to really pinpoint the sound but I noticed the rubber boot at the transfer case was torn and the iron rod seems to be resting at the base of the shaft. Could this be the problem where the teeth on the transfer case rod is slipping causing the sound?

    You have a head/cylider issue. I just went through it and your problem sounds the same as mine. Good luck

If you only hear it over bumps it is the heat shields under the truck. i have an H3 06 also and had the same sound at 30k. does the "clicking" sound get fast as you drive faster? if so, it could be the teeth, if not, look for loose bolts on all your sheilds under you truck.

My 1998 toyota corrolla, starts makeing a clicking sound when I turn to the left. I want to know if it is cv joint? or boot, or could it be the axel or maybe the ball berrens.

sounds like a cv joint> best thing to do is change cv's on both sides that should solve it. not so easy to do as a first timer unless you have done it before. check the control arms aswell

A chatter on hard left or right turns. Been told may be clutch pac in transfer case.

The person that told you that was right .You can try to drain out the fluid and put in new with a additive .This problem should not do any harm to the transfer case it is just annoying. :)

Clicking sound when in 4WD

Of coarse

Anytime a CV Boot tears the dirt & water off the
road ruins the joint & you have to replace the axle,
thus the clicking.

6 months you knew that an didn't care

As they say pay me now or pay more later

In sharp turns, right or left, front end shinmies/shakes. Is this a trnsfer case problem..? Have a 2000 Grand Cherokee with Quadra-Trac

I don't remember what the cut-off year was when Jeep changed from standard universal joints to C/V joints but your problem sounds a lot like a bad end joint on a front axle shaft. "U" joints are "X" type...CV's have a rubber boot covering them. If the boot is torn that also could cause the CV to fail but unless they are really bad generally they get real noisy first before they get to the point of binding.
Only way your transfer case could be doing that is if you have different size tires in the front or rear.
Usually a bad transfer case will make the whole vehicle shudder, even going straight.
If you have X type joints, don't go by how they look... you need to remove them to see if they are binding.

Clicking noise while driving, changes with speed, sounds like coming from transfer case or drive shaft

If indeed it is coming from the drive line area, it could be a bad universal joint. It may also be a torn boot on the front axle (just thought I'd mention this), or it could be the transfer case chain has a lot of slack, causing the chain to hit against the transfer case housing internally, this would be the worst case scenario.

99 hyundai sanata the rubber boot is dark in spots . on my rack and pinion.checked powersteering oil leve .it is full. no wining,at starting or i have to replace now

Pinpoint the location of the leak before you replace any thing. It could be coming from anywhere, example: valve cover gasket, rad. overflow bottle, leftover oil from oil change. Fluids can really fly when you driving sixty.

Transfer case motor for push button 4x4

i have a 1993 blazer 4.3 w code 4x4 with a 4L60 E . my truck wouldn;t go in 4 hi or low. so i changed the transfer case motor and it works fine now. If you turn the ignition key to on but not crank the engine and open the driver door and push 4 hi button, you should hear the transfer case motor cycle for 3 or 4 seconds every time you push button and the light will flash until it goes in 4wd If the 4 hi button light doesn't flash during cycle then it could be a bad switch. if the transfer case motor won't cycle it could be a fuse or a bad transfer case motor . Hope this answers your question.
