Steering Vibration - My Journey
KTM520EXC:
Roger That, Captured Nut on Frame, I appreciate the heads up, I'll put a fair amount of spray lubricant in that area.
KTM520EXC:
OK, so major storms in NorCal last weekend, so only tackled the strut arm bushings.
Corners better, but "in town" vibration is still there. Concerned factory lower control
arm hardware is "not" factory, so when the weather turns to unbearable by Nor Cal
standards, lower control arms are next on list. Want to enjoy some country driving
before weather turns.
KTM520EXC:
Finally getting around to tackling the lower control arm bushings, but I need some guidance.
I can't get a bite on the nut that is "in" the lower control arm towards the front.
I tried a 14mm/15mm/17mm/19mm, no luck. The outer bolt just spins the inner nut
continuously and it appears that a nylock nut is on the bolt, so I am guessing these
bushes have been replaced before.
Any help appreciated !!!
Thx !!! Michael
KTM520EXC:
Disregard request, looks like there was a captured nut in there originally and someone replaced with Nylock nut.
The only way to get it out was to wedge a really long screwdriver to stop the nut from turning. Not fun, but
got it out. The previous person who was in there last, failed to remove the captured casing, so there was no way
I could get a socket, or wrench on the nylock nut only 3 of the 6 sides were accessible, hence the wedge method.

If you want to fix this the correct way, you'll need to weld a new nut up in there. It's not all that difficult, 4 little tack welds (one on each side) should be good enough. The tricky part is getting the tip of the welder up in there. You may need to cut yourself access holes in the unibody rail, then plate them back closed after you are done.
It's either that, or deal with a non-welded nut next time you need to get that lower control arm out.
