NP/NV231 Specialist

[MercManche]

I am offering services relating to transfercase maintenence, parts & information. Should you need to know anything about or need something answered I can help.

 

I am not a shop or anything, but I have successfully built, rebuilt and repaired many 231s. If anyone needs help, shoot me a PM, the least I can do is try to point ya in the right direction!  

Qualifications:
1x Built custom case using a combination of 3 different transfercases to build a nearly unbreakable jeep transfercase. (6k on my YJ no issues)
4x Repairs, meaning seal changes, pump replacement, chain checking & replacment, etc.

3x complete rebuilds, top to toe (minus gears) I still have a drill driven output shaft I can use to run a basic NVH test to make sure its within spec. (perks of working with a NVH engineer lol)

7x case repairs, front/back half, tail cone etc. 

 

Costs:

Full rebuild (Bearings, seals, chain & pump): $150 labour + parts.
Single parts: $ |Varies based on whats needed|, what transfercase etc.

SYE install $50: You provide parts, I preform the labor. Takes no more than 30 mins to install.

Diagnostics: $ Free to $10 ,  My NVH testing is an amplitude track based on a known, good rebuilt 231. A full NVH test requires a multi-million dollar testing station. To be honest, a mechanics stethescope would tell the basics, or a good ear. If you just have general questions shoot me a PM or leave a response, that is of no cost.  

*All service is assumed to be on a unmolested, unmixed 231J (Jeep) series transfercase, I will NOT work on mixed or other transfercases as there is too much risk. Shipping of these cases is around $100-150 itself, fastenal shipping is the cheapest method. Local members to Georgia or passing by zip code 30542 can simply drop it off and pick up same or next day. 

Requesting Quotes or Information:

Use the following format:

Year, Make and Model of Vehicle case is from & the drivetrain in front of it.
Photo of Red Identification tag (Parts or service), I will not provide information without the Identificiation tag. (Red tag above fill plugs)

 

After that information, please ask your inquiry. 

Example:

1995 Jeep Wrangler YJ 4.0l HO and AX15

If you need parts, I have about 3 cases worth. If you need service I am capable of up to full rebuilds, but I would prefer to be a parts guy as I may not always have time. 

 

 

Could you post specific services/parts and prices?

I’d like to get a puller for that dumb pilot bearing for the front output shaft.

I use a 3 jaw pilot bearing puller. That bearing is very annoying to deal with.
