Can anyone suggest why Johny Joints should be used over Heim Joints (or vice versa) with A-Frame setups on GQ's?? Or any other application for that matter??

At face value, the Johny Joints are greasable and appear sealed to prevent dirt entering the joint (but are they rebuildable??), but Heim Joints seem a bit more "industrial" and appear stronger. Any thoughts on this??

if you are talking about the actual a-frame pivot on the axle, the johnny joint should theoretically be better. heims don't like side load, give a heim too much side load and the sphere will start to push the linings out.

Yep, thats exactly what I was getting at. I imagine the same can be said for the axle and chassis end of a 5-link setup too?? Is there any particular preference for a manufacturer for Johnny Joints?? Snake Racing, Big Balls etc or are people making their own??

Cheers for the help.

the panhard deals with the side loads on a 5-link.

Cool, so Heim Joints could be used reliably on a 5-link then.

Any other traps for young players that I should know about while I'm here? Have seen a few different arrangements of A-Frame rears......they all seem to work effectively, but is it better/easier to have the pivot bracket and bushes in-line with the axle and the arms welded at an angle from the bushes........or the arms and bushes at 90 degrees to each other with the bracket at an angle from the axle?? Faark, does that even make sense??

Also, has anyone tried the dropped radius arms from Snake Racing yet?? How do they compare to the 5-link?? Do they achieve what their write-up suggests??

? are you talking about an a-frame design, or a 4-link set up??
there is a lot of words there, but i can't make any sense from them!

More the 4-link setup really. Was alot of words, but not alot logic.......my bad .

We're just throwing ideas around at the moment.......everyone over here in NZ is too tight with their information and not willing to share secrets about their setups or the mistake they've made and then changed. So all the info we can get out of you guys is much appreciated!!!

no worries, i have 4-linked my GQ, and it has had a few design revisions, and changes and shit.
i'll try and grab some photos of it next time i am looking at it. the gq chassis works quite well for this. move the lower links to the inside of the chassis and move the mounts on the chassis about 350mm forward. bring the uppers to the centre o n the axle, and roughly to the same point as the original lower link mount on the chassis, but inside the chassis, and higher.
i know that makes no sense in words, so i'll try to photograph it.

Thanks man, some pics would be much appreciated. I'll send you a PM with my email addy. I've been perving at the pics of Gabriels setup too....thats one sweet rig!!

We think we've got the power-plant issues sorted for the truck......we've been experimenting on our own trucks (turbo diesels) to see what works. We're on a budget (isn't everyone!!), but its handy that my driver is a diesel mechanic and turbo tech head!! We're probably going to stick with CT26 turbos as thats what works on ours.....is just a shame they're Toymota bits. Have pulled the head off the fuel pump and fitted a larger 12mm rotor head from a Landcruiser fuel pump to deliver more fuel. Have smashed on an aneroid too. Still having issues with getting enough air, but hoping a 4" intake will solve this. Need to do a few more home jobs for mates to pay for more tinkering!!! Oh, will possibly be running LPG injection also!
