NP205 Transfer Case Bearing Issue

September 19, 2017 - Author: CourtneyN

Question: Howdy, looking to rebuild my transfer case, thus looking at your rebuild kits. The problem is when I shift into low range 4 wheel, I get a grinding noise and it won’t engage or will pop out real quick if it did engage. 4 wheel high seems fine. So any info as to what you think is wrong would be great. Thanks


Answer: From your description it sounds like the front bearing in the front output shaft is failing allowing it to pop out.  We would suggest that you start with our bearing rebuild kit it fits NP205 in Dodges 1989 to 1993 is our part number TRSBK205D, your cost is  $237.97 plus S&H.

If you need addition technical help give Scott a call 888-824-2012 he can help you.  To place the order call the same number and ask for Adam, Connie, or Joe. You can also visit our website to order,

NV4500 & NV241D Conversion

June 28, 2016 - Author: CourtneyN

Question: Perhaps you can help me with some information or a source for it.  I just installed an NV4500 and NV241d from 1999 Dodge Ram diesel into a 1995 Dodge Ram diesel.  Standard cab, eight foot bed.  The trans came with the front drive shaft.

The rear slip yoke is a smaller diameter (it came off the standard auto and transfer case that was removed) and the original 1995 drive shaft is too short. In your knowledge did this combination exist from the factory? Is there a source for the yoke and proper shaft? I have seen two piece shafts and center bearing shafts that I assume are for the long bed.  My real question is do you know what I need?  Any help would be deeply appreciated.


The  diesel trucks came with both NP241DLD and NP241DHD transfer cases. That being said the 1999 NP241 DHD will not work in the 1995 due to there being no speedometer provision in the transfer case.

1994-1996 NP241DLD use a 32 spline output  with a speedometer in the rear oil pump housing and 1997 and up NP241DLD do not

1994-1996 NP241DHD use a 32 spline output with a speedometer 1997 uses a 31 spline large diameter with a speedo and 1998 and newer us the 31 spline without a speedo provision

The best option is use the old NP241DLD and switch the input shaft over to a 29 spline input to bolt up to the NV4500.  We can provide the following parts to assist with the conversion.


27 Shaft Input 29 Spline 6010n Bearing Narrow MWTNP4797029-R $122.92


23 Input Bearing (.630 inch Wide) MWT6010-N $20.66


Shipping charges will be added.   You will need to find a driveline shop to modify the drive shafts   We have such a shop in Maple Grove, MN that can help you their number is 800-444-0755.

Call the sales department to place order at 888-824-2012, if you need additional technical assistance ask for Scott he can help you. Visit our website to see more parts for the NV4500 and NV241D at

Rebuilt Transfer Case

April 18, 2016 - Author: CourtneyN


I’ve just rebuilt the Transfer case after “notorious rub” issue (152,000 mile) output shaft will not turn by hand. Need to know is this normal before reinstall on the truck…?


The output shaft should turn by hand, when in the transfer case is in 2WD, the input and rear output should turn together. Make sure the rear snapping is seated in the bearing groove. Something is bound up and I would not recommend installing it that way.

NP205 Customization

June 22, 2015 - Author: CourtneyN

Question: Hi, I am looking for an NP205 to put behind a GM 4×4 NV4500 for my project truck. I think the simplest option would be a customization round pattern, 32 spline input with an Advance Adapters spacer. I think these were used with the TH400 transmission. Is this transfer case one that you can provide or build or possibly recommend alternatives? Thanks!

Answer: We can build a customization round pattern NP205 but there will be tail modifications that you can make on the NV4500 to be made due to the space needed for the shift rail.  A 712529 bracket will also be needed to mount the shifter for the NP205 your cost $75.00. This transfer case is part number TCGM003 cost is $1000 outright plus freight. Visit our website to see more NP205 Transfer Case Parts or to let us help you with a part customization please call our experts toll free 888-824-2012.

Does the vehicle year matter?

June 9, 2015 - Author: CourtneyN

Question: Was wondering if a 2000 transmission would work in my truck. My truck is a 2001 Chevy Silverado 1500 5.3 Liter 4×4 automatic. The 2000 is exactly the same as my 2001 but just different years.

Answer:Because of the electronics it will not… 2001 is all by itself. We recommend part number 400-3889 for $1314.50 plus a $600 core charge it will correctly match up with the electronics for that vehicle year. Visit our website for more product information

1968 Corvette T5 of T5WC

June 4, 2015 - Author: bartbarton

I have a 1968 Corvette.

Question:  I’m looking to drop a T-5 in my 68 vet. Was T5NWC_MTFRD033looking for a world class 1352-176, -182, -196, or -213. They all should be about the same. Was also wondering what kind of torque they are rated for. The engine I am running is a mild 327 with a rear gear of 3.08. I’ve seen some rated for 300 ft lb of torque and others for 600 ft lb torque. I don’t want to tear it up. I see that most of these sat behind a 5.0 liter F-body so I would think they would work behind a 327 with about 350 Hp.

Answer:   The T5 will be a little light for the 327CID with 350 HP it will work if driven only  and not a drag race car.

You would want the T5 Camaro World Class unit and this would have the mechanical speedometer provision required. There would be drive shaft mod’s, cross member mod’s and poss tunnel mods to be made

These are hard transmissions to come by but we could find and rebuild one cost would be $1700 outright no core required, plus freight. Give Scott a call toll free 888-824-2012 he can help you. You can find a complete list of transmission, rebuild kit and hard part for T5 transmissions on our site.
