Same Here glad someone started this post good thing I am not driving the '91 for a while....I think moser should put up a install page on there website to let everyone know what has to be done... I put mine in it was easy didnt think nothing of it...I did check the pion angel when I put in my spohn tq arm..geting the tq arm on the rear was the hardest part for me.. it was like the rear was to big to fit it was tight to say the least...after bending the stock tq arm with a 2.11 60ft

 

that is fuggin bs..........if a company sells a product that is advertised as a replacement for a stock part, retaining stock features.......it should have any possible warning as to other parts that might not function properly.


its obvious from the responses that just about every car needs the driveshaft modified in order to work, so this is not an isolated incident.


no good company should leave details like that up to the 3rd party installers to notice......that is just too risky, since everyones mechanic differs in experience/skill/quality.

 

Well guys it could be worse. THis is fairly minor issue....

ANyone here rember KTRE? They were the first to offer a new 12 bolt of a 4th gen. Many, including a good friend, bought one. The money was taken and over a dozen were never shipped! They were $3,500 each back then.

Some people NEVER got there money back.

This realy is some thing that the Installer is responcable for. Yes it would be nice to know up front. I agree it should be a warning. Then again if you look at the people who figured it out and the people who missed it there is a pattern

Good luck all. I am going to go enjoy my Moser today

 

Well guys,

Rob Moser asked for this link to this forum. Within a few hours he replied that he will definately change the installation guide and will also research the approx. length that is required to come off. I wouldn't doubt the shaft coming part of a kit sometime soon.

I am glad FINALLY Moser has made note and is doing something about it.

 

Im gonna have 1/2" taken off mine..Should be perfect..Glad I didnt slap some Slicks on there and take it to the track..Ive only had street tires on it

I'm thinking somewhere in the neighborhood of an 1"-1 1/4". . . I have an LPE DS and I can't even remove it without some serious frustration. . . I have no doubt its jam packed against my tailshaft of my tranny. . .

 

I have a strange 12 bolt and now wonder if I'm in the same situation as the rest of you guys.

When I installed my strange 12 bolt (myself) I had plenty of room from the point of putting my 1le driveshaft into the transmission and then having to pull it back to fit on the yoke. If I recall it was 1-2 inches. I've had it out when I changed my clutch and also install/reinstall was painless

What has me thinking now is that I do get the loud clunk here and there over bumps. When I changed my rear end fluid after 1000 miles, I noticed my TA cover was rubbing against my sway bar. I figured that's what was making the clunk. Also, the clunk was always in the back of the car, I never heard it in the front.

I have a 348 Ujoint and a 1350 yoke. Should I be worried about my driveshaft lenght? Also, what is the correct process for measuring the driveshaft length? What points are you supposed to measure from (to center of yoke exactly from transmission point with driveshaft pushed all the way in?)

 

My strange from what i have seen is all good. MY sway bar was originally hitting the cover, but i just moved the sway bar mounts around a little and got it to clear no problems.

 

So is the strange not effected?

 

While I agree that it is always a good idea to "check things over" when installing a new part, I can see where one could make this mistake and overlook this problem. Afterall, you are buying a rear end which is being sold specifically for the 4th Gen F-Body. If it is NOT a direct bolt in (and it obviously isn't) then Moser SHOULD include the steps necessary to make it work.

How hard would it be for Moser to include this little tidbit of information with the rear when it is sent??? It would save people thousands of dollars? I'd be a bit miffed if I found out Moser knew of this problem yet didn't tell me about when I bought a rear end made specifically for my car. Also, it's not like you are buying a Global West Track Link torque arm. i.e., when you go to bolt this item up and realize there are no bolt holes in the rear driver side seat area, it is completely obvious that you must drill these yourself to install the torque arm. However, when installing this rear end and the drive shaft actually FITS and WORKS then I don't see how Moser shouldn't be held at least partially accountable... remember, this is a rear end made specifically for the car it was bought on.

I don't know... I guess it's just a shame Moser can't include a piece of $0.01 paper indicating this NECESSARY modification especially when it may not be completely obvious to the average Joe Blow backyard mechanic.

 

exactly!

do not let the reputation of your company rely on the installation quality of a 3rd party. make sure all the possible steps/modifications are listed.

 

I still think Moser should put something on their site or in their documents with the product to alert consumers to the fact that this is not a direct bolt in and does require the DS to be shortened.

 

Thanks for alerting Moser to this thread. I'm sure it will save a bunch of problems for everyone from here on out. If the folks from Moser read it, they may also want to include some of the little hardware necessary to complete the install, and make note of which shims are which in the packaging. I had to scrounge some metal clips for the axle too.

The product is great as far as I am concerned. Just a note about driveshaft length and perhaps a brief description as to how to check it and why would be a help. Moser cannot be responsible for this as a tranny change will change the length of the stock DS in these cars and I'm sure that many of their customers have non standard configurations.

Again, thanks for getting them involved. I started to a couple of years ago but forgot to follow up with them. It is really great to see something constructive come out of a bad situation instead of the usual vendor bashing that happens too often around here.

 

Sorry to bring this back up from the dead but, has this problem been solved?

I'm helping a buddy install a Moser 12 bolt in his Z this saturday and was just curious as to the specifics of it. Has Moser made engineering adjustments to the product to make it work with stock DS?

This is on a 6spd car and I'm not sure which Yoke is on it.. any info would be great

 

I ran my stock DS for 5mnths with no problems but I didnt abuse the rear-end at all or take it to the track during that time. I have since shortened it 3/4" and added a steel shaft. Your best bet is to call Moser and ask them but I would also check how far your DS is from botteming out in the tranny..
