Difference between rose joint & tie rod

[CB0569]

Hi there all
i have the usual steering wheel wobbles.
Wheel bearings-GOOD
Swivel hub bearings-GOOD

NO MOVEMENT DETECTED ANYWHERE.

I've been told to change one of the tie rod ends with a ROSE JOINT.
How does this work any different as they both move etc etc?

Please help me understand.

What are the usual wobbles? when you hit a pot hole, down hill, going straight etc ?

are you running caster plates, drop arms or drop boxes ?

[CB0569]

I can be driving along then all of a sudden the whole vehicle shakes,the steering wheel shakes violently.I have to stop ,then when i get moving again it is gone.
This doesnt happen all the time and it does it with my both sets of tyres,so that rules out wheel balance.
I have castor plates.

rose joints may be illegal on road? and I cant understand how a TRE could induce the wobbles?

search the nissan section hi and lo dude.... not knowing the history of your car there's a thread about your problems at least once a week!

panhard rod bushes or radius are bushes are they flogged out.

[JeSTeROCK]

Do you have a return to centre dampner ?

its a nissan gq/gu i am guessing.

often its a little of everything

1 check panard and drag are parallell
2 check castor is correct and adjust for lift
3 check for play in all bushes
4 i found tyre pressure to be the difference after i did everything and it still happened - i droped my tyre pressures and it has be 100% since. if you run big tyres they bounce big time. with 35's i ran 22 front 18 rear on road (petrol ute). I now run 20 front and back with 36x15.5 r15's and its still sweet even without a steering dampner. your car should drive 99.9% without a dampner don't use it to hide bad panhard/ castor. rember bigger tyres have greater surface area so 15psi is like 30 on a std tyre. cornering will always be a little vague with low pressure. its a trade off

lastly if it had cheese cutters it prob has tow in std. I think the wide wheel package came std with tow out so check with a specialist

also to answer your question a rose joint is essentially a tie rod end in double shear rather than single shear like a TRE. so rather than having a captive bolt that forms the joint there is a ball with a hole right through the centre. A bolt can then be placed through it. they are not generally dust protected and wear / rattle etc but are often used in race equipment as they are captive and are contained when they fail rather than pop off like a tie rod. they are not really suitable for retro fitment to a gq etc as without a tapered bolt or a double shear pitman arm they will be more sloppy.

Dude - Pretty sure a rose joint will not pass an engineers cert. Tie rod ends have a taper for a reason. It stops slop in the joint. If you go for a rose joint, you'll never be able to tighten the 2 pieces together properly.

mate are all your wheel nuts tight and if you have mags or the like are the wheel nuts the right ones just an idea.

I'm from South Africa. Did a spring over axle conversion on my MQ Ute. Throw out the whole steering draglinks and all the TRE's. Fitted 4x Rosejoints. They improve articulation major! Also much stronger than TRE's . Cost me only 20 Oz dollars per Rose joint. Here in the RSA u can do what u like and drive on the highway.............ANYTHING GOES!!!! As long as the lights work, the tyres got grip 2mm deep and its licence is paid up for the year.........U r free to go!!!!

true...but you get shot at when someone wants your motor!!

TURPS- The Pandard rod and bushes are only 12 months old,and the radius arms just move when a pry bar is used.

JeSTeROCK- No i dont have a return to centre steering dampener,mine goes from the chassis to the steering arm

bru21- I run 31's on road @ about 32 psi and MUDDIES @ 40 psi on road and 18psi in the bush.it does it with all the pressures.

Webbie- I have 7" steelies and they have the standered wheel nuts.

I have found that wear in the panhard bushes combined with a little too much castor is usually the prime cause (although any number of other things may contribute).
The panhard bushes may only be 12months old but I would still replace or check them - especially if they are urethene.

I think the rose joint idea may have related to replacing one of the panhard bushes to eliminate any slop (compared to rubber for eg). I saw this on a GQ that was in the current 4x4 Monthly mag (a silver one with simex tyres).
It sounded like a good idea to me and I was going to look into it for my Patrol. Not sure of the legalities but the panhard is not a steering component so it may be OK.
Any thoughts or ideas?
