get a length of thick walled tube, about 4" long (depending on amount of adjustment needed), with an inside diameter of the upper arms, tap out the centre to a fine thread, cut your arms in half, thread them accordingly, screw back togeather using your new tubes, and get some hex nuts to lock the adjuster with. should cost no more than ten bucks, unless you get ripped on the steel tube

how bad are the shaft angles ATM?
I take it you are using the yellow coils?

[Ryan]

nah i bought 4" lift king springs in the front and dobsons in the rear, apparently off the part numbers on the yellow ones they were only 2" so i went 4............ shaft angles are ok on the front but the rear is the trouble,,,,,,, getting vibes when accelerating and decelerating.. noisy when coasting how much longer do u think i need em??

jack the car up, take the coils out, lower it back to ride height with the chassis supported, put the jack under the pinion part of the diff housing. Then you can unbolt one end of the upper arms, jack the housing to where you want the pinion flange to be and measure how long you want the arms to be. Then cut and shut them with some tube or whatever.
Extend them as little as you can get away with because it can bring up another whole set of problems with the coils rrubbing on the shocks and the shocks getting hammered by the bumpstop plates etc, if you roll the diff back too far. Extending the lower arms as well is a good idea, but brings up a whole lot more work as well.
Thats weird about the coils, they were bought as part of a 4" kit from Mannell Motors about 18 months ago. When I put them in the truck it had 2" Old Man Emu coils in it already, and the new springs were at least 50mm higher??

what sorta pinion angle is good???? (remember im only used to an old MQ hehe) at the moment it looks fairly steep

If you are running the standard shaft the pinion unui angle should oppose the t/case output uni angle pretty closely. You may need to drop the t/case crossmember 5 or 10mm..

Adj top arm available from SJ Leslies in Melb and also Cheezy.
You will need to shorten top arms not lengthen . Prob by about 15mm

ok i got my adjustable upper links today (delivered by bigballs)
problem is that when they are ajusted as small as they can go, they are still about 6" longer than my std ones??????

if they actually delivered you the upper links they are way too long, your pinion flange will be pointing upwards. Id make a call and check things out.

6"???, Fark... They wouldn't happen to be roughly the same length as the lower arms would they?? ROFL....

[bogged]

So how did ya go Ryan???

did ya call Liam?

[big red]

sound like you got adjustable lower arms.
they are stronger than original ones so i would put them on anyway but at the standard length unless you have smaller than 35 tyres, in that case you could adjust them.

[Ryan]

yep liam called me first thing thismorning, upper arms will be here tomorrow they were lowers that were delivered, i would have still used them but both the upper ones are bent so i gotta change them
