After I purchased my 70 I wanted to upgrade to a 12 bolt. Original 12 bolt were a bit pricey so I decided to get a Moser 12 bolt. Just to be clear I have used Moser products before and I was a Moser dealer when I had a shop. I ordered a 12 bolt with 35 spline axels, 3.73 gears, Wavetrac carrier and axel retainer bearings.
Due to health issues the project was delayed. Finally last November I started trying to install the rear.
First thing we noticed was there was grit in the axel tubes. This sucked since the carrier was installed by Moser. I raised one end of the housing and carefully washed out the tube then raised the other end and did the same.
I got around to sliding the axels in, don't know why they didn't install them at Moser, the passenger side went in OK but the driver side wouldn't go in. It sounded like it was bottoming out.
I contacted Moser and they said I should tap it in with a mallet. I wasn't real comfortable with this but did it any way. No luck. Another call to Moser and was told to use the axle retainer plates to pull the axels in. Again I wasn't comfortable with this but did it any way. No luck The axel is still about 1/4 inch too far out.
By now it Christmas and they are shut down.
So I decided to pull the carrier, I really didn't want to do this since it was already set up but I felt I didn't have any choice. So after pulling the carrier I installed the axels and measured from the axel end to the tube end 3-15/16". I put the carrier and shims on the bench and measured the depth, 3-3/4"! The axel was 3/16" to long and was bottoming out. Just like I thought.
So I took the axel to a local machine shop and had it shortened by 7/16", I wanted a little extra room just in case.
I just called Moser with all this and all they said is they would make some notes in on my invoice. That's it! They didn't even ask me for my name or telephone number. (I purchased the rear thru a dealer not directly. So it's obvious they have no desire to get back to me or do anything to make it right.
I'm very saddened about all this. Like I said earlier I was a Moser dealer back in the day and met and talked to Greg Moser many times, he would be very distressed about the lack of support.
