I have the 98 5.2 ltr D w/4x4 but the indacator lights are busted they say part time 4x4 and 4x4 neither work how do I know when im in either and if either actually work?Als o is it better tone in or out of Over drive cuz Idk


Ps it seems to shift much better out of od but my boss says "its a gas saver" (od)

 

Change the bulb. It will be 4wd part time with the 231 transfer. Hi lo 2wd. Engage 4hi turn truck in tight turn and the tires should churp as they want to grab. Tow with od off!

 

in order to test 4x4 simply shift into gear and try to turn (as stated above) if the truck slows down and stops or chirps the tires as you push the gas to keep it turning you are in 4x4 part time. you may not need both lights depending on which transfer case you have in the truck. what does the shift pattern listed on the top of the 4x4 shift lever say on it?

as for driving with OD:

under normal driving (empty or passengers only, no trailer) you can drive either way, will not hurt the transmission, turning OD off while under 45 or so will stop the truck from shifting into 4th gear prematurly, make sure to turn it off on the highway in order to save fuel (OD only saves fuel at highway speeds).

when towing keep OD OFF in order to save the transmission from overheating by constantly shifting in and out of OD as you go along.

 

Thanks for the replys guys, first ill say the shifter says 2H-4H-N-4L.

Second my D will usiualy chirp around a corner also pop and make a buckeling feeling/sound most recently an odd noise I can't describe while reversing. And turning other than this stuff and a squeeling sound when i turn hard and an alignment that needs to be done Im quite happywith my D

 

you will only have one of the two 4x4 lights in your truck (they used the same dashboard in the trucks which had the full time t-case which is why the second light is there).

as for chirping around a corner that could be a few things, but do the test that i described above and let us know what the results are. if it does this while the shifter is in 2wd and it is behaving as if it were in 4wd then your tcase isnt disengaging properly you will need to find an empty parking lot to back up in, while backing up turn the wheel, the idea is to release axle bind and allow the gears to unlock

 

just for ref... if you did have a full-time transfer case you would have a **** that looks like this---->

 

So basicly I have part time 4wd?

 

Thanks ill do this in the am before work, luckily theres a large parking lot across the st

 

yes you have part time 4x4 which means you should only be using 4wd in low traction situations such as snow, gravel, mud sand ect, not on dry pavement.

 

That's what I thought I wouldn't use it unless I needed too anyhow. This morning I did that test in 2w it did slow down like and buck but its hard to tell about the chirp my power stearing squeals when turned all the way to either side not too loud tho. Im told this is normal due to the stress of the tight turns. Also I turned in reverse at caring speeds in both directions ill do this again after work and see if there's a difference. If the transfer case isn't disengaging 4w properly will the dash light stay on? I ask this because ill be changing the bulb today
