Default Front End "Clunk" Any Ideas?

Seasons Greetings to All.

I have a clunk in the front end of the Patrol. Turning left is when it happens and it can be heard as well as felt coming from the right hand side.

I can make it happen most of the time even say going left and right down a straight road. Imagine going through witches hats slalom courses.

The drag link is relatively new and the shock bushes appear sufficiently compressed.

Radius arm bushes appear OK too.

Any thoughts to point me in a direction would be appreciated.

Cheers

Justin

Not sure what sway bar you have but one of the rod ends on the rear sway bar is clunking when I turn. If I slalom it does it both ways.

Cheers to you too Justin.

I had same issue, check bushes from front panhard and the steering damper, they appear in good condition they can have play.

I fix it like this:
Loosen up the bushing nuts from panhard, the rubbers will regain their original position, leave a few minutes and then re-tighten the nuts.
change the bushes from the steering damper.

If you have adjustable drag link, check the U nuts, sometimes the Us get movement.

And check the nuts from steering box...

Had a better look today with jemmy bar in hamd.

Zero movement from panhard.

Drag link and steering bar OK.

There is some movement in the steering stabiliser and it's leaking a bit.

Managed to get movement out the front bush on the radious arm right side.
Left side I couldn't budge.

Cheers

Justin

I chased one for ages. Went over stuff a number of times. In the end it was the radius arms that was the problem - the bolt on top of the diff on the drivers side specifically. Pulled them out, cleaned up the threads, and put them back on with washers. Fixed.

My engine mount knocks on the drivers side, especially when doing a loaded l/h turn. Chased it for ages not thinking it was it because Ive replaced all the body, engine and gearbox mounts. Even though it's a genuine part about 18months old and maybe 10000km, it must be soft and comes together touching metal on metal. You can see the wear marks. Also downhill in low 1st it knocks it's tits off. I'll have to replace it again one day unfortunately.

To be totally honest wouldn't have thought to check engine mounts!

Might as well while I'm under there.

Cheers

my front end clunk was a trans mount... rear end squeak went away after replacing radius arm bushes. underbody sounds can be deceiving.

Check steering damper isn't hitting anything also body mounts my drivers side has started to make a noise but only when off road.

Looks like it was the front bush on the front radius arms.

Undid the bolt, checked everything, bit of grease on the thread and retightened.

So far so good.

Also I swear the steering feels much nicer without the return to centre damper.

Grabed a Gabriel one from SCA for $64 on special.

Thanks for all the input fellas.

Cheers

Justin
