It is absolutely wrong Mike. No one proof read that article. There is a early style that ended in 2/35 . The late style ran to the end on Auburn production. Few internal parts are interchangeable.

The bitterness of poor quality remains long after the sweetness of low price is forgotten.

Hi Curt, In the last Newsletter there was a article about making new components for the dual ratio dif. At the very end it said components would not fit a speedster. My understanding is there is no difference between a 35/36 Auburn Dual Ratio, whether it be any body style except the ratios. Do you have a different opinion?

When using this method of determining rear ratio remember the left rear axle is the drive axle. That's the one that usually breaks.

Thanks for your reply... I've become aware of this problem in general but I'm not clear on what gets welded (when that is possible) and what gear must be replaced.
My 8-105 has about 92k on the odometer. The differential seems to be fine--I believe it remains in the low ratio and am not sure if or when it has ever been taken out of the low ratio. I'm also not sure that the differential on the car is original. With the rear wheels off the ground, the drive shaft is easily turned by hand. When is is done, the number of revolutions of the drive shaft produces the number of tire turns that suggests the low ratio spec for a 12-165 model. Makes me wonder if the original was replaced by a 12-165 model diff.

If you have a 32, 33, or 34 V-12 car or a 32 or 33 Eight then you most certainly have to repair - the axles are fairly rare and as far as I am aware parts are not made (perhaps Stan Gilliland stocked parts at one point ? or perhaps someone in club I am not aware of makes marts or ?),

If you have a 34, 850, 35 851, or 36 852, then you also have the problem, but there tends to be more supply of back axles and most people have been getting along via welding, but on occasion there is a car that just cannot be welded on again or .... As mentioned, there is a project in the works and optimally the price should be probably in the $500 or so range for the gear (what I have known people striving for via other gear projects and they faced same issues of people not wanting to pay much more than that), but I think they were having trouble at $1,000 or so now a (or so was the case when I last heard about the project). A very worthy project though as repairs are just that - repairs.

Is the 2 speed rear axel for the 1933 8-105 interchangable with the 1933 12-165?

I am at 513-478-1887 or [email protected]

David Yancy is looking to reproduce gears - 1-916-505-4692

The only problem is most people do not drive their cars and as a result he is having trouble finding enough people to get pricing down - this is an expensive proposition.

2 speed rear axle was created by Omar1447
Are owners of all Aburns with 2 speed rear axles have been or will have to be welded internally to repair a problem that has been known in the club for years. It seems a tempory fix as it is doon?
