Thread: MS II front end cross memeber

Tweet

As Tech and Shine mentioned, the aftermarket manufactures moved away from the Ford control arm and strut rod design that used larger and more flexible bushing materials and now have issues with stress cracks in the crossmember using the small control arm bushings that are very rigid. This transfers more of the impact to the crossmember and brackets, causing the fatigue and cracking issues. Some manufacturers have better designs than others, but all may eventually crack out depending a great deal on road conditions and miles driven. 1/4" wall crossmembers welded to 1/8" wall frame rail; where is the crack going to start? Just a thought.

The best thing about the Mll front end is it was designed for the Pinto but they call it Mustang because of the Pinto fuel tank issues-


The overall best part of the design is the geometry package that is about the best you can get for a sensible street driven light weigh vehicle. Bump steer, brake anti-dive, etc.


But, as hot rodders do--------put it anywhere ---------in any size/weigh vehicle--------


I think that the situation that puts more strain than anything else is the twisting of the whole package under heavy braking plus hitting an occasional bump at the same time-imagine that someone has your arm twisted way around very tight and then hits you very hard in the shoulder---------these oem cars had little 13 inch wheels , small brakes and light weight---


A front suspension that stops a 3000 lb car from some high speed down to a quick stop is similar to a rear end/drive train that has to launch that car at a drag strip??
