OK, I've got a full build thread going on about Rufus, but I wanted to single out this issue. I've got a serious suspension rebuild effort going on with the front wheels (rear will come in a bit) 1. New coil-overs 2. BBK 3. Inner and Outer balljoints up front 4. Adjustable drop links 5. Lower control arm bushings 6. New lower control arms (the inner ball joints were frozen solid Rufus is a 2005 (13 year old) JCW and I'm pretty sure that the suspension (other than a new front swaybar replaced due to rust a few years ago) is stock. I've had a hell of a time with siezed bolts, but the large bolt that holds the shock body to the wheel carrier was the worst and the head snapped off (despite a week soaking in penetrating oil, applied 3-4 times). That's my problem... It's the bolt up near #6 that pinches a receiver area of the carrier on to the lower portion of the shock body. The head snapped off cleanly on both sides. I've got a couple of options: 1) I could buy new carriers ($400), but it would probably also need CV boots and maybe wheel hubs (another $400+) given the rust that is there. 2) I could drill out the old bolt and run a hardened bolt through the new smooth hole, putting a nut and washers on one end to pinch the carrier on to the shock body. This would be the simplest solution, but will it hold? 3) I could try to thread the hole and go back to the stock M12 bolt (it has a special smooth part in the middle of the shaft so the 2 parts of the carrier will pull back in together). I'd probably use a kit like this: https://www.amazon.com/Thread-repair-helicoil-damaged-thread/dp/B01MPYFF8E/ref=sr_1_8?ie=UTF8&qid=1520796856&sr=8-8&keywords=m12+tap+1.5 Thoughts?
