X5 4.8 integral link stripped thread

[svvg]

Just been replacing very worn rear bushes and control arms and also the rear swing arm bushes. When I removed the bolt which holds the integral link into the wheel carrier a load of swarf came out with the bolt... needless to say the new bolt (I'm replacing all bolts bushes and arms) started to go tight when I went to reinstall everything, and then went loose... and out came the stripped threads from the rear wheel carrier...

Bit worried I may need to replace the rear wheel carrier unless I can remove it and maybe helicoil it??? The bolt which attaches the integral link to the wheel carrier is supposed to be done up to 100 or 105nm...

Grateful for some advice - mate of mine was skeptical that a helicoil would take that torque and has just suggested an insert instead (am waiting to hear back on what an insert is!).

Grateful for any helpful advice!
