on the LSD that I've got in my car, a 3.45:1 from an ED XR6, its got two mounting holes for the upper control arm .

Now, I know that the XR6's had different mounting/trailing arms, Im just using the stocko ED ones.

Whats the best mount to use? the upper one or lower one? .

anyone understand what I mean? lol .

Had a tip of that it could be the top ones that are used for stock control arms.

Hmm ..

I think that it has a lot to do with your pinion angle. You gotta try and keep the pinion and the output yoke parallel to prevent power losses, friction and damaging vibration.

If your car is lowered you use the first (front) hole, thus keeping the yoke angle in line, If your car is lowered and you use the back mounting point the front of your diff will be facing down, and wearing out your Uni joints.

On the other hand if you use the front ones and your vehicle is stock height the front of the diff will be facing up, and will wear out ur uni joint and cause vibration etc.

Just remember the diff angle i'm talking about is when the car is sitting on the ground, not jacked up by the chasis.

Hope this helps

OK, just read your post propperly, same thing applies except the bottom one would be for lowered and the top for standard height. if you think about it, it makes sense. Using the top hole the control arm is pulling the front of the diff down (making it face the road) and by using the lower hole you are lessening this affect, hopefully making the front of the diff face forwards.

my car is lowered using lovells springs, I've found out that I need to use XR6 control arms for the lower mounts, and the standard ED ones will fit nicely into the top ones .

Its fixed up all the problems using the top mounting bolts, no more creaking sounds ... all good ..

Yup ... next time I take the wheel of the car I will show you .. and take a pic .. But yup .. using top ones, I think you need to use EF control arms if you need to use the bottom ones.
