Area Representative z7 Posted July 27, 2002 Area Representative Share Posted July 27, 2002 When investigating the source of a klunk (not A-frame, that's fixed) I found that all the bolts holding the prop shaft to the diff were loose!! Can anyone tell me what value I should torque them up to, please? If it makes a difference, I have a Quaife LSD (the exact model of which I don't know), on a Ford live axle.

Area Representative z7 Posted July 28, 2002 Author Area Representative Share Posted July 28, 2002 Thanks guys. I had thought about locktight, too. But is there any reason not to use it on a nyloc nut? Cheers Link to comment Share on other sites More sharing options...
Blatman Posted July 28, 2002 Share Posted July 28, 2002 I'll bet the nyloc has become contaminated with gearbox/diff/engine oil at some point, rendering it useless. It shouldn't happen to loctite/threadlock........oh, and replace the nylocs as well. Belt an' braces.......... Link to comment Share on other sites More sharing options...
Grim Reaper Posted July 29, 2002 Share Posted July 29, 2002 Nyloc nut??? Not sure if the Live axle is different, but i've just bolted the prop and the diff together using some "special" blue bolts and some Studlock loctite to 42lb/ft. What's so special about the bolts apart from they're blue?? The Meaning of Life Part VII;Death Link to comment Share on other sites More sharing options...
felix.klauser Posted August 1, 2002 Share Posted August 1, 2002 Nylocs can't really get contaminated by oil or grease; they still work as the nylon insert is deformed by the bolt's threads. However, an over-used nyloc will loose its functionality. Loctite needs to be applied to clean (free from oil, grease and old loctite) and dry threads otherwise it will be contaminated and not work as intended/required.

scooby dooby doo Posted August 1, 2002 Share Posted August 1, 2002 the blue bolts come ready covered in loctite. There's not meant to be a nyloc on the back. The question of how the threadlock on there knows whether to lock or not when you're torquing them up the last little bit is a tricky one though... any ideas 🤔 HOOPY Link to comment Share on other sites More sharing options...

Peter Carmichael Posted August 1, 2002 Share Posted August 1, 2002 Adil.... Seeing as those bolts have seen considerable frapping vibrations I suggest the only safe course is to fit new bolts. ISTR a certain vibration near my kidneys... Link to comment Share on other sites More sharing options...
