I like to better understand the differences between the "stock" Olds Toronado and the "stock" GMC MH front suspension.

The one that sticks out and that I do know about is the hub.
A 5 lug to 8 lug. However, I do not know what or if that hub was used for - other than the GMC MH.

What else is differnet on the "Stock" front suspension and was it used on any other vehicle?

Thanks, Tony

Corleyw,

You might want to drop the I - in front of was in my quote. Very Happy

Your Quote of: "Of course the Caddy Eldorado comes to mind immediately" does not tell me the differences in parts used and from those parts that are difference what those parts were and what they were also used on other than the GMC MH.

I have never seen a Caddy Eldorado with 8 lug truck hubs and rims. Laughing

The hub of course is different as is the rotor. The knuckle has a different size lower ball joint and related taper. Since the width of the front clip is different, anything to do with that is different.

It is my understanding the GMC was designed to use as many existing dually truck parts such as brakes, hubs etc. as possible. Once you leave the transmission none that I know of are the same as the cars.

Mike,

Lets see:

The inner CV would have to be for the Toronado trans.
The axle can be custom and the outer CV has to mate/fit the hub they used.

But I'm not sure what GMC truck in the 70's had a FWD hub much less axles with CV joints?

I can picture how they can use the truck rotors and calipers but not a hub, bearings or front axles. But then again I do not know every type of truck on the road. Very Happy

Yes Mike I understand. Smile

I was simply trying to get a little more than that and I was hoping for a little back and forth dialogue.

But okay - lets leave it whatever part they could. Smile

EDIT - Sorry Bob. I meant to say thank you before in my other post and almost forgot this one too. My Bad..... Shocked

You're going down the wrong path. There are no truck parts in the mix--front or rear. The rear brakes and bearings are B car wagon parts and the front are modified E car (Toronado/Eldo). Trucks had solid front axles with conventional U-joints.
