Suspension Arms and Pins

You need to double check the suspension arm holes and suspension pins to make sure they do not bind.  If they do bind, your car will not handle consistently.

The first step is to run a reamer through the suspension arm holes to make sure the holes are straight and the proper sized.  For this step, I decided to use a tool from Hudy.  When using this Hudy tool, be sure to rotate the reamer slowly while sliding the tool in and out of the holes.  This will remove any extra plastic that could cause binding without removing too much material.

The next step is to polish the suspension pins.  I recommend doing this with 2000 grit sand paper.  I carefully chuck each pin in a drill so I can spin the pin in the sand paper.  If you use a drill, be careful not to over tighten the chuck since that will score the pins.

Then use Blue Magic Metal Polish to polish the sanded pin.

Here is a picture with one pin sanded and polished and three pins that are completely stock.  The sanded and polished pin is smooth and shiny compared to the stock pins.

Here is a picture with all four pins completely sanded and polished.

Here is a picture of a sanded and polished pin mounted in a perfectly reamed suspension arm.  The suspension arm now moves without any noticeable friction, yet there is no play or slop in the fitment.
