Single Stick D18 Not Getting Into 4 Low

Hey guys one of our members didn't get to play today because the single stick D18 transfercase wasn't going all the way into 4low. Might try some quick stuff tomorrow morning but we just didn't have much to work with today. It has a locker in the front and warn locking hubs. One thought was the hubs weren't reassembled correctly but I'm not convinced.

I think we just need to jack the front up and start spinning stuff. What are your suggestions for order of trouble shooting?

 

Well, on a single stick, if it's in low, it has to be 4-low, so was it in low? Was the front DS turning? If so, and you don't think the front end was pulling, then yes, look at the hubs.

 

Ok, I'll do the basic troubleshooting tomorrow. I think one of the venders had a set of drive flanges that will work if needed.

 

No need for a jack just yet
Unlock the hubs
Put the t case on what you think is neutral
Does the driveshaft spin easy?
If it does, lock both hubs
Does it still spin?
Yes=problem, no=ok
Put t case in 4wd low with hubs unlocked.
Does it spin? No= ok, yes = fuct
Now how drive it. Does it drive like it's low?
Yes = good, no = bad
If any of the above equalled problemfuctbad
It's time for a tear down.
BTW you neglected to describe the vehicle
Year make and model please

 

well I really don't see where a locker/hubs have anything to do with
shifting the transfer case . as howard said . linkage is problematic due to wear

 

I'd start with plenty of oil on the linkages. Get out and get under, see if there is any obstruction by the body or whatever. Simple stuff first!

 

What Pete said. I always liberally lube the whole shift linkage area. That wagoner was so dry it wouldn't go into Low but, that WAS a different animal. Start simple.

 

Did it work in 4 HI?
