I've an ’02 Chev 2500 which has a manuel 4X4 shifter. My difficulty is that 4hi gained’t have interaction. 4lo appears to perform just high-quality, axle engages, lights within the dash arrive on, I'm able to listen to front axle actuator participating, but After i attempt 4hi almost nothing looks to happen.
Nicely, that’s one which I haven’t read but. The “ATS†fuse (that is marked “ATC†on this schematic) provides 12VDC to 2 huge orange wires for the TCCM (marked as pins C18 and C19 to the schematic). As I reported, I haven’t witnessed this problem in advance of, so I haven’t traced that Element of the technique. I'm able to only think (yeah, I'm sure!) which the because these wires supply 12VDC, They may be accustomed to operate heavier factors such as the encoder motor (5VDC, that's the light guage orange wire, is useful for logic — ie. to operate the “chips†on the circuit board). Hopefully, you can see where I’m likely with this particular. I’m just trying to consider it logically — When the fuse is blowing that supplies 12VDC, what during the 4WD technique would use 12VDC?
I employed a single wheel since the reference and modified the tubing so which the drinking water amount as with the dust cap, and took one other stop of the tubing to each from the 3 other wheels and built absolutely sure the water matched the identical issue on Every wheel. For those who jack the car to put spacers beneath the wheels (as opposed to driving up on them), ensure you jounce the suspension to settle it before you make any measurements (this isn't important to look for amount). It can be very good to note that some sort of slippery area must be applied underneath the front wheels. The front wheels should be turned to evaluate caster along with the suspension should not be sure up wanting to make that change. I set a set of the one/8" hardboard spacers under Every front wheel which were very slippery in opposition to one another.
Now, if you DO hear the “click-simply clickâ€, then your TCCM is Operating and looking to change into 4WD — the problem, IMO, would then be With all the module that is definitely about the transfer scenario (I neglect the phrase for it at this moment) — it is a simple “motor†set up that simply just moves the transfer case gears to the proper manner.
Now where the heck that matter is…I have not got that much. Hope this aids all of us expand our know-how on these excellent substantial maintance motor vehicles!
$ten to fix your 4WD — brilliant! Thanks for sharing that details with myself and my audience — I’m guaranteed it might help a couple of folks save a lot of $$$!
That’s some pretty good data to own. You should do let me understand how you make out While using the encoder motor substitution.
If you select to get started on a brand new Discussion board matter, you can connect data files for your article. If you choose to add an image, it will create a new topic in my blog (which I will then move to be provided in just your unique put up).
Ideally, this will likely set you off in the proper way. Make sure you let me know what you discover as it might be of use to another person listed here Down the road.
Low groaning sound at 40mph and 60mph sounded like front wheel bearings, but was basically a bearing while in the axle help. My mechanic worked with me to interchange just the bearing ($38) vs the assembly ($325) in addition labor.
one) it is possible to pull within the cable to have interaction the passengers facet website hub — but it is going to disengage after you release it as vacuum Ordinarily holds the diaphram closed, which retains the cable, which keeps the hub engaged.
The grey with black stripe wire (GRY/BLK) at pin 5 would be the 4Hi sign wire — when pressing the 4Hi button, this wire should really go incredibly hot (I haven’t take a look at the wire, so I’m not sure if it’s applying logic amounts (+5VDC) or battery power (+12VDC) — In either case, it should be warm when the button is pressed.
How to test if the change is terrible? I’m undecided which switch you’re referring to, but no, I never. I’d just Google it usually to locate what I’m seeking. Anything which i at any time wanted to check was observed by Google.
I listen to loud noises although driving, I'm certain it is not the engine.. Relatively absolutely sure the Front wheel bearing really need to get replaced. Do I want to exchange both of those front wheel bearings?
