my car is eating Uni joints and the only thing that I can find wrong is the pinion angle is a bit excessive, are there offset bushes that I can use to correct this until I get some adjustable arms?

cheers

Noltec do them - not cheap and I'm not sure how much the offset is.

cheers, so the rear bushes are the same as the lower control arm for the front?
if so I am looking at $163 for the bushes.....

I bought a set the other day from a place called Car Torque here in adelaide, pretty sure they were $100 a pair. Give them a call, I have a feeling the prices on the website arnt accurate.

What about some solid urethane and turn down and offset drill to suit....just a thought.

[rodomo]

if you packed up the gearbox mount would that improve the angle?

[rodomo]

The floor would get in the way fairly quickly.

I dunno?
We lifted wraiths g/box nearly an inch?

Whiteline also make adjustable upper and lower arms.

KTA104 � Adjustable upper $360 ( $325 club discount )
KTA121 � Adjustable lower 655mm $297 ( $260 club discount )

The McDonald Bros arms will not fit if you diff has been made using Torana brackets. The Whiteline arms will fit with Torana mounts on the diff.

Whiteline is not owner of Nolathane... or vica versa

I prefer Noltec myself
And Edelbrock upper arms

What brand uni joints are you using? Is your car an auto?

Check the simple things before spending money on things you don't have to.

yes it is an auto, the brand is Toyo and it only lasted a bit over 2 weeks but I was doing a lot of kilometres.

lifting the trans mount will make it worse as the pinion is pointing down.
I am pretty sure that my diff actually uses the end of lower trailing arms as the upper mount on the diff so the McDonald Bros. ones should be fine, or the McCormick Father+Son ones that I am probably going to use will be fine too.

for the moment I am looking at relocating the front mount for the lower arms a little bit further forward which should fix things for now

The angle opf the gearbox output shaft and the pinion axis should be paralell. Generally the pionion is pointed upward and the gearbox is pointed downward. If your pinion is pointing too far down lifting the rear of the gearbox will help overcome your problem.

[ls2lxhatch]

Once your get adjustable arms you really need a digital level to set the uni angles accurately.

A good article on pinion angles.

Looking at the pictures of the arms it looks to me that the bracket on the end of the arm that goes onto the bush on the diff needs notching/clearencing on the bottom.

I was not prepared to modify the McDonald arms to the extent required for full suspension travel. It was easier to just buy the Whiteline arms.

[makka]

I think that the LH/X ones are a bit straighter than the UC ones.
I have just fitted some like scottya's ones, dad made them up out of some seamless chromolly that he had lying around.
they seem to have fixed my problem, so far so good!

Gotta love having an engineering minded Dad hanging around!

[Toranamat69]

I am pretty sure the LX and UC upper trailing arms are the same part.

The fact that the rear bracket is offset just means the true arm 'centre' line runs a little diagonally through the arm.

That raises an interresting question though on your arms Makka - how did your dad make the arms to suit the dogs leg arms you had before, I would have thought you would need the bracket at the diff end of the arm welded on at an angle or there would be some twisting of the bushes on the diff housing required to bring the front af the control arm round to where the bracket is on the body?
