All,

As some of you know, I've been negotiating on a 2006 cab over the past week or so. I noticed this 06 was manufactured in the middle of 05. Would this car be more prone to IMS issues (like an 05') than a later model 06? Or did all 06's come with the larger IMS Bearing? The dealership took delivery in August of 05, so I'm guessing it was built in May or June of 05.

Thanks for your help.

 

hi wcs, you should be fine... the larger single row bearing i believe commenced production after late feb '2005 (based upon the class action lawsuit). mine is an '05 build in late march and my vin does not fall into the lawsuit category of effected cars.

with that said however ive read that some 05's built after feb 05 have the weaker m96 style bearing but it should be nothing your 06 should have to worry about.

hope this helps and congrats!

 

I wonder the same thing as my MY2006 car has a 7/05 build date. Glad to read the above response!

 

Who ever has the messed up bearing will get a letter in the mail from what i read on rennlist. Mine was born in july2005 but its a 2006c2s

 

Thanks for your help guys

 

I agree with MYW...My build date is April 05 and my VIN is not included in the class action...I have confirmed I have the larger single row bearing. the MY06 cars should all have that newer design bearing. I've heard it's possible still to have IMS failure with the upgraded bearing, although much less likely.

 

yup. if out of cpo and if you are keeping the car for the long term you can always do an ims bearing upgrade from LN when you refresh the clutch at about 60k miles. and from there on in you have complete peace of mind (not that it should bother you much or at all right now even)

 

Base engine (3.6) has designation "M96", can have the smaller IMS or revised larger bearing, you will need to know your engine number in order to determine which one you have:

Engine (3.6) number up to M96/05 69507475 has the smaller IMS bearing and Engine number from M96/05 69507476 has the larger revised IMS.

"S" Engine (3.8) has designation "M97", can have the smaller IMS or revised larger IMS bearing:

Engine (3.8) number up to M97/01 68509790 has the older IMS bearing and Engine number from M97/01 68509791 has the larger revised IMS.

The smaller IMS bearing can be replaced, this requires removing the transmission in order to get access to the bearing. The flange uses a 13mm center nut.

The larger IMS bearing can also be replaced but a tear down of the engine is required. The flange uses a 22mm center nut.

 

awesome post. rep points to you

 

excellent info. quick stupid question - where is the easiest # stamp to find? do i have to crawl under? (which i do regularly but tonight when i check, i am hoping it's easier/found topside or elsewhere!)

 

You don't have to crawl under its pretty visible on the driver side just bring a tooth brush and water to scrub it down some so all the numbers will show when you take a picture with yor phone.

 

AWESOME info... checking mine today thanks to this glorius info. Sank youz!

 

Exactly where is this? Under neath on the drivers side or access from the engine lid?

 

Driver's side. Underneath. Pretty easy to spot once the grime is off.
