Axle Housing U-bolts
« on: November 03, 2019 - 01:40:38 pm »
I'm a little confused on the size I need for the u-bolts that hold the axle to the leaf springs on my '72 Challenger. It looks like I need a 3 inch inside diameter to fit around the axle, but the holes on the mounting plate, under the leaf spring, are 3 inches center to center (meaning the inside diameter is smaller). Is that normal, do you have to compress the u-bolts a little to fit the plate? Or am I missing something?  :clueless:

You're not missing much. U-bolts have always had a certain blacksmith aspect to them and it isn't uncommon to have to use a BFH to "adjust" the bolts ends to fit the bolt's plates. Just don't beat the bejeezus out of the threaded part.  :cheers:

Good to know. Glad to hear I'm not losing my mind.....yet. Why would I EVER think anything might be easy on this project. The good news is that I do have a BFH. Thanks!
