Annoying clunking/knocking noise update!

The front radius arm to axle bolts were not very tight at all!!! (Thanks to
whoever suggested that!) Could move them easily with a regular spanner! Have
to use large torque wrench to tighten them. I only polybushed the vehicle a
couple of months ago and they are loose already!! I replaced all the nuts
and bolts with new ones at the time. I will replace them again.
Still gonna put new front shocks on today anyway.

Cheers, Stew.

Stew Hi,

Maybe fitting self locking nuts would help.

Take care

190Nm is what you should have.

They were tightened to the specified torque using Nyloc nuts. Thats why I
can't understand how they got loose.

Did you retighten 'em after installation once it had been bounced around a
bit?

This is a popular misconception. Nyloc nuts have nothing to do with
keeping a bolted joint tight - all that they do is stop the nut falling
off the bolt once the joint has failed.

In a normal bolted joint the bolt is stretched and keeps all the
components tightly clamped together by virtue of its elasticity
(provided, of course, that the joint has been correctly designed in the
first place).

Among several things that could have happened in your case are that the
joint was compromised from the start by having paint/rust on the joint
faces, joint faces that were not flat, holes were worn so that the
already small contact areas were even smaller, lower than desirable
specification for the steel material for the nuts/bolts etc., etc..

In the longer term you may find yourself having to reclaim the holes in
the axle brackets so that the bush inner sleeves seat fully on one side
and the nuts/bolt heads seat fully on the other. It also helps if the
holes are not excessively large in relation to the bolt diameter.

It's a land rover tha ran out of warranty some years ago, so naturally all
of the above are definitely factors!!! ;-)

Stew Hi,

AFAIK suspension and bushes nuts and bolts have to be re-tightened after a
while and especially after the bushes have been installed.

Actually during the camel trophy events it was always recommended that the
crews should tighten as many of the suspension and bushes bolts as possible
at the end of each day.

Take care
