Lower Control Arms 1971 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

exploderjim · 07-01-2010, 02:27 PM

I was wondering I ordered new lower control arm shafts for a 1971 Cheyenne Super BB 402 1/2 ton long box C10 and received shafts with screw type ends on it. I took mine apart to find mine were the ones with rubber bushings. When I looked up the parts the bushing style was like the 73 bushings. The alignment shop ordered the correct rubber ones from Moog and said mine were not interchangeable. Is this some how a different set of lower control arms or was there another option? I'm confused as the part supplier says the screw type are the only ones for my truck and clearly they are different. Any info would be appreciated.

Ours have the screw type ends. Sounds like your front end may have been swapped out at one time?

The threaded bushings were used through 1972, so your control arms and shafts must have been swapped by a PO. Unless you are doing a stock resto or just plain like parts that need to be greased, keep the rubber bushings. They are maintenance-free, and when they finally do die, they cost less to replace than the threaded type.

Thanks for the comments. I assumed it had been changed. Just difficult to order parts when you don't know whats been done. What is a PO? Again thanks for the comments.
