The transfer case is what supplies the power to the front wheels.

Actuating the front diff doesn't supply the front wheels with power, the transfer case does.

The transfer case supplies power to the front diff. It always supplies power to the front diff, it doesn't matter if the vehicle is in 2wd or 4wd.

The front diff engages to supply power to the front wheels.

Here's my diagram of the front diff. Anyone have any ideas? Part nomenclature is at http://home.comcast.net/~firepaw/blazer.html/frdiff.doc

I hope you don't mind....I blew up the picture and added the nomenclature to it.

OK GREAT GUYS> SO WHAT IS THE F'ING BANG ALL ABOUT???????
Had TCC Motor Changed, solved some problems but their is still a F ing Bang. Spider Gear, worn out Shaft? What is the Bang? To be more specific, when it disengages it is a bang that feels like you just hit a Pot Hole With the Right Front Wheel.

WHAT IS THE BANG. Please do not responde with how something goes into or out of gear if its the front or rear dif, or if its just 2wd 4wd.

JUST TELL US WHAT THE FING BANG IS. Can you do that, Thank you.

Did you check the tread depths on all your tires? Any variation from even one tire will cause the symptom you are having.

Have 2 new ones in Front and 2 older ones in back. ASked a tech about that and he said it si only an issue if they are differnt size, and that thread depth will not afftect it that much. Areyou sure you dont work for Goodyear? Just kidding.

Honestly, this could be the issue.

With the backs being different than the fronts, this could cause the clunking and the lack of immediate disengagement.

On a 4x4 you replace all tires, not just two.

wolfox · #24 08-16-2005, 03:02 PM

I ditto that sentiment - all tires must match in size, wear level and tread patterns for there to be trouble free 4x4 operation. Oh, and rotate them every 6k Miles, when you change your oil and filter so that they continue to wear relatively evenly. When it's time to get new skins - get *all 4* replaced at the same time.

If you would pull your f ing head out of your f ing ass and read the f ing thread, you will see that I posted the most common f ing cause in f ing post # 4 and Swalt followed it up with more f ing details in f ing post # 8. From what we f ing posted you should be able to f ing realize that if you have two new f ing tires on the f ing front and two raggedy ass f ing tires on the f ing back... that is probably causing your f ing bang. Try not to be such a tool. Can you do that, Thank you. f head!

So, are you saying that I should look into replacing the 2 back tires as well? Just kidding, I saw your advice and thought that you guys were full of shit, still do to a point, well maybe not full of shit as much as just a little purest. Anyway I will try them, Sam I am. And if it doens't work which I F ing dont think it will. I will be forced to abuse you till you cry like Nancy Fucking Kerrigan, BIATCH>

Stay Tuned. This is just too funny;l

wolfox · #27 08-17-2005, 01:20 AM

What's really funny is watching the center differential on a Subaru bind up and burn out when someone with the same line of thought as yours comes along. You can't just swap one tire for new on any axle on 4x4/AWD cars and trucks. I blew a tire on my Scooby a few years back and got the one tire replaced. Same type and tread as the others. However, since it was of a larger diameter (because it was newer) she was binding and making the car lurch in low-speed, parking lot like turns, or sharp right hand turns to launch down a side-street. The solution was to take the car to a specialty tire shop that had a machine that would *lathe* the new tire down to match the diameter of the other tires. The binding/chatter going around a turn disappeared. We're all seriously not making this sh*t up my friend - funny or otherwise.

What Dies Everyone Else Think

firepaw · #29 08-18-2005, 05:20 PM

Now I need a little more help. If I bend over, can a couple of you guys give me a hand pulling my head outta my butt. I went down and put 4 new tires on the beast today - problem gone. The old ones looked plenty good to me but I DID NOT measure tread depth. Hmmmm.

There is however, still a couple of questions bothering me that someone may be able to clear up. When you switch out of 4hi what exactly is the sequence of operation of the x'fer case and front diff? Does the X'fer case vac switch get actuated after disengagement of the x'fer case or does everything happen simultaneously. I can't seem to understand how there can be a load on the front diff gears when the input is decoupled.

Anyhow, thanks a ton for the help and the laughs, I appreciate both greatly.

Tom
