View Full Version : Panhard rod & death wobbles!

Just thought I'd share my experiences on a P38 steering experience I've had over the last week.
I have been doing a few longer trips of late and noticed the steering tending to tramline, or want to follow grooves in the road, along with a bit of a knock developing.
Sometimes things wear slowly and you don't really notice until it starts to become obvious.
I had a look and could see the panhard rod bushes were looking a bit worse for wear, so I got some aftermarket ones and pressed those in last week.
The steering felt much tighter, but when I got over about 60 or 70 km/h, the dreaded death wobble reared it's ugly head. I've never experienced that before, but I knew what it was straight away.
From everything I've read, often panhard rod bushes fix this problem, but not in my case.

I found movement in the steering shaft coming from the top uni joint, so I replaced that, which improved the steering feel again, but the death wobble persisted at the same speed.
I tightend the steering box a smidge to try and tighten things up a bit, got the front wheels balanced, rotated the front wheels to the back, checked the shocks and steering damper, all to no avail, still the death wobble at the same speed.

I finally caved and took it to my local Land Rover specialist, who had a good look over the front end and found the lower ball joints needed replacing, along with a couple of tie rod ends that were on the way out.
But to my surprise, he found the panhard rod bushes had a lot of movement in them, even though they were new.
He showed me them on the bench and the rubber was just too soft to do the job properly, he thought that may have caused the front to bounce from side to side, setting off of the wobble.
He fitted genuine bushes which are much harder rubber, and I'm glad to report it is driving much better now and no sign of death wobble.
I'm off to get a wheel alignment tomorrow morning to make sure everything is ok.
So the moral of the story? Use genuine panhard rod bushes!
Cheers, Pete.

I've replaced the panhard rod bushes with genuine Lamforde ones. Was good for about 8000km, now death wobble has returned worse than ever. As usual while you're on holiday.

Ahhh bugger! Of course you are trying to enjoy a holiday while that starts happening!
Have you checked your ball joints? From all the reading I did, the most common cause of death wobbles seems to be a combination of ball joints and panhard rod bushes.
For some people a simple wheel balance cured the wobble, also a dodgy steering damper can allow enough movement to set things off. One guy pulled one end of the damper off and found about an inch of movement before any dampening effect kicked in. I checked this on mine, but mine was fine.
Also a steering alignment might help, but you have to check everything is ok before that of course.
Hope you get it sorted.
Cheers, Pete.

As usual while you're on holiday.It might pay to re-tighten the panhard rod bolts. If not cranked up to an incredible torque (spec not to hand), they won't hold the bush correctly.

Well. It turned out that's exactly what it needed. Took it to British4x4 in Adelaide, and checked everything out, and found the bolts were loose.
