Hi,

 

When you mount this pin back in to the front subframe it obviously goes through a hole large enough to take the circular section 2/3 of the way down the pin. I know that the end of the pin has a squared off section that should line up with the metal section at the top of the hole to stop it turning but is there  a washer/ lock tab that goes in there as well?

 

Also, mounting the adjustable lower arm with the offset bushes, working from front of subframe to the back, should the lines on the offset bushes be pointing down the arm at the front and then up the arm at the back?

 

Thanks,

 

Rod

  The large diameter head of the pin simply locks into place in the subby by itself, no other parts are present at that end of the pin.

 

  Instructions for the bushes are linked on the product page at Mini Spares:

 

Fitting: 
In both cases the bushes need to be properly orientated to achieve the correct angle of fitment for the offset steel sleeves. The bushes are therefore marked with a fine line on the narrower side of the bush flange (check top and underside of flange). The front bush (nearest front of car) should be fitted with this line pointing down the centerline of the bottom arm towards the wheel. The rear bush should be positioned with it's line 180 degrees the other way, so pointing in towards the centerline of the car. Trial fit the bushes and bottom arm pin to the arm before fitting to the car - the pin should fit easily through. If the bushes are not correctly aligned the pin will not fit easily.

 

 

  Do you know that you only need the offset bushes if you have altered both camber and castor?

Hi,

 

Yes. Thanks for confirming what I thought on the pin.

Also, you'll want to tap the big round-with-square-side head into the hole on the subframe. If you try to pull it through by tightening a nut on the other side, you'll risk stripping the threads.

Hi beware,if like me you bought pattern part bottom pins, you may have to dress the fat end with a grinder as they werent a great fit, try them in situ first.

Did anyone else have trouble getting the pin to completely slip into place? Did you guys have to completely remove the arm? Or just jack up on the bottom of the arm?  I am stuck...

The pin won't slip fully home without some effort, the bushes need to be compressed into place or they won't be doing anything. Normal practise is to use a mole wrench to press it home and hold it in place while you get the nut mostly fixed. Remember to not fully torque it until the car is on its wheels, to allow the bushes to rotate to their normal position. If you torque it at full droop the bushes will grip and will then be distorted in the normal rest position, so they will be overloaded at bump and will fail early.
