Im trying to duplicate the moser 9" bolt in rear end, I have the bracket for the torque arm, I ordered the GM small with ford big bearing ends

The question is, How can I use my factory disc brakes. Moser is saying I have to use the 98-02 backing plate. Are there any other options, I read somewhere that the factory backing plate could be machined and drilled. If so, does anybody have those measurements.

Oh ya, And Strange says there is a .520 ofset. Does that mean one axle is 1/2 longer. The measurements on the website show the centerline .520 away from the pinion. Is the pinion centerline where the .520 measurement is. Or is 1 axle tube .520 longer.

 

If you got the 7900D housing ends then the disc brake brackets should work. As for the offset, all GM car rear ends have the pinion offset 1/2 inch to the right. The axle length on the 9 inch is going to be different on each side anyway just because of the design of the rear end.

 

i got the strange ones, h1143

 

i used my fatory brackets had them machined to hold the bearing in place then drilled new holes to attach the bracket to the housing eb miller sells the brackets to do the same i like his better cause you can remove his bracket w/o unpressing the bearings off i'm gonna get a pair of his

 

Do the Strange housing ends have a place for the factory axle seals? The Strange housing ends that I have seen didn't have a place for these seals and the axles will usually leak oil. This is why I like the Moser housing ends. They will accept the original type axle seals and don't leak. The Strange ends that I have seen rely on the O ring on the axle bearing to seal them, which often doesn't work.

 

I just looked up the Strange H1143 housing ends and they do not have a place for the original type axle seals. The Moser 7900D ends would work better. These housng ends will accept the axle seals and they allow the bearing to sit flush with the surface of the housing ends so that the disc brake caliper brackets don't have to be counter bored to bolt onto the end. The other housing ends are going to make the bearing stick out 1/8 inch, so the caliper bracket will have to be counter bored before it will bolt up.

 

well crap!, i have them now so i have to use them. I could silicone them for additional protection. Now about the offset. the moser 9" incorperate the 1/2 " offset for the pinion? Most 9" rear ends are 2" offset at the carrier, one tube would be 2 1/2" longer than the other one?.

 

The pinion will be 1 inch closer to the right end than the left. That is 1/2 inch offset from center.

 

Alright. So I take the pinion center guage, Put the tape measure in the center notch, subtract .520 to the measurement of my axle tube on the right.

 

You will also have to add that much to the left.

 

alright. can u get the lower control arm/shock mounts since u are a dealer?

 

Moser won't sell them like that. You will need to cut them off of a 10 bolt.

 

Moser does sell the lower control arm brackets seperately. They also sell lower adjustable control arm brackets. Big Gear Head give Moser a call. I'm pretty sure that they started selling them that way this past year.

 

Thanks for letting me know. I was not aware of that. I know I have had people wanting to buy brackets for the Chevelle rear ends for several years and I could not get them before.

 

I talked to moser, they sell the lower control arm brackets, I never asked about the adjustable lower control arm brackets, I might just have to ask them and order those.
