I was driving about 70 mph on interstate with no trailer maybe 2-300 pounds in box driving 5th gear earlier I heard some rattling, then later I was driving and all of a sudden rpms dropped and nothing in 5th 1,2,3,4th still work fine, I'm guessing the 5th gear nut came off no grinding sounds where heard I have just over 163,000 miles I have had it about 2 months had 152,000 when I got it out of texas. I have read I can do it while the tranny is in and I would prefer right now cause I need to get it back on the road. does anyone have digrams or links or any info on taking care of this or is it too late because gear is already off? also where could I get a part DC or part store or what preferably local so I can get it right away.
TIA please help it is emergency.

 

Go to www.sixstates.com and order the nut with the set screw. You will have to call them and ask for the guy with the knowledge of NV4500 HD transmissions to get the correct nut. Do not get the gland type nut, it will fall off again. When you install the setscrew style nut, use red loctite so it does not fall off again.

 

I got one yest. at dc it is the set screw type w/ washer and red loc-tite $47. what I am wondering is it said if my gear already came off the instructions say I need to replace gear?? I can't til;l monday and I need to have it on the road by monday. does anyone know if I h=need to remove the transfer case?
BTW it is snowing right now here on MAY 2nd darn wisconsin dusting on the ground and coming down pretty good for the last hour maybe. just my luck and I have to work on it outside, yeah

I lost mine as well a while ago. I went to the dealer and got the updated nut for $47 bucks. I didnt hear any grinding in mine and the gears ended up being fine, I have heard both but I would definatley look at it and look at the gears to make sure before you spend any big bucks.

well have it down to transfer case out and 5 of the 8 bolts on tail end cover loose and out 3 are to stubborn and one at least is stripped any ideas how to get the stripped bolt out? I might just drop tranny and take it somewhere to have bolts removed but then I would have to get together the money for a clutch since I would have it out? anyone have ideas?? TIA

 

Half the cost of a new clutch is the labor removing and replacing the tranny. Even though you're doing the work yourself consider your time worth something.

 

well stripped bolts equaled taking tranny out to get bolts taken out at the shop decided I will replace clutch fingers looked pretty worn some heat scarring on the plate and flywheel, plus while its out I will replace instead of going through it again soon. going to replace slave to not from dc though they wanted $340+ went to bumper to bumper and $65 sounded much better and it the same sealed unit. have to find a clutch asap though like get it by tommorrow fast. anybady have any 2 cents or advice let me know.
