We got our first snow of the year today. When I was on my way to the store my rear end fishtailed so I put it in 4wd. Nothing. The "4x4 High" and "4x4 Low" lights just flashed a few times, then went out. The front wheels never engaged. Any idea what's wrong here? I did a search, but came up with about 800 threads with "4x4" in them.

 

same thing happend to me..i think its my gay vacume hubs thoe

 

2 things might be

1) PVH hubs are crap... time for AVM even if there not just get them its worth the $100...

2) clean the 4x4 shift motor..

 

Couldn't have said it better

 

How do I clean the shift motor? Is it safe to take it apart, or would it be better to just get a new one?

I have no idea what you just said about the hubs. PVH? AVM? What are those?

 

PVH - Pulse Vacuum Hub (these are the stock, unreliable hubs or lockout)

AVM - is the ONLY aftermarket manual lockout.....they replace the unreliable PVH stock hubs......


Do a search on here for AVM

yes its find to take apart, and unless you have $400 ish so i have heard to get a new one...

PVH: Pulse Vacuum Hubs.. its whats on your truck now. they are crap...

AVM is a brand that sells Manual hubs for your front end.. easy to install about $100...

there is tons of topics on these hubs on here...

 

they are only $100 new Zach.....I just replaced the one in mom's Explored

 

Thanks for the help guys. It's dark and snowing now, so I'll look into this tomorrow.

 

the shift motor on the transfercase?

 

ya first clean the motor because its free.. if it still doesnt work... or in general just order the hubs there 100000000x better then PVH

 

they are now Rugged Ridge hubs, same p/n as the AVMs from tellico, but i just got my new set and they say rugged ridge
no biggie, just felt like throwing my $.02 in there

 

Quick question on the hubs. Will I lose the "shift on the fly" feature if I get these?

 

yes and no...

you have to just go out and lock the hubs then click the **** into 4x4... like say you know its gonna snow the night before lock the hubs so there ready to go in the morning... some guys just drive all winter with them locked so there ready to go.. will loose a little MPG doing that tho...

 

And what are your thoughts on the "Hub Mod" ?

 

pretty much the same thing as locking those hubs all the time...

 

yup it was the t-case motor

 

not bad.. didnt know i just heard one just why i said so i heard haha...

 

and you can find them on eBay for roughly $30.......

 

thats how mine are setup, but then again i have no more vacuum lines

 

and cause unneeded wear on the front end......I don't lock mine unless I THINK I will need them......it ain't. Nothing to get out and lock them in

 

the 4x4 engagement motor went out on my ranger, if you're hearing a clicking after you start up, it's probably that. check the 4x4 motor fuse and see if it's blown, took it to a buddy and he found it shorted out and replaced it, but the 4x4 works for awhile then i unplug it from the 4by pcm and it works for awhile then stops so i may have to replace the 4x4 pcm, not fun.

i just spent half an hour getting up a hill with 8 inches of snow on it, someone came behind me and bumped me up the hill. this snow sucks.

 

You got that much out there? We've got maybe 3" here. Still slicker than whale snot in an ice flow.

 

yah, not easy to get through on a steep hill haha, made for interesting times.

 

I got the Warn Manuals put on they work great
