Hey all,

I just installed my upper/lower DSE arms. When i tourqe the castle nuts down, the cotter pin hole is above the castle nut. SO i get no engagement from the cotter pin.

Is this a common problem with DSE arms? Is there a good fix for this?
Taller castle nuts? spacer/washer?

Confused.

This is normal. The purpose of cotter pin is to keep the nut from falling off, not from preventing the nut from backing off from its torqued value.

I need some factory documentation on that one. I have not read it one way or the other, but this is how i see it... If the pin is in the slot, the nut will have a more difficult time backing off from tight. If it is is not in the slot, and the nut comes loose, no way that little pin will stop it with the knuckle bouncing off of it.

i'd look for a taller nut. I ran into a similar thing, but on the spindle nuts on a brake conversion kit.

I have also installed quite a few reproduction FTend parts on other cars where the nut was too short, and luckily was able to use the OE nut. If I couldn't, I guess maybe I'd drill or use spacers if enough threads show. I've never seen an OE unit where the pin was on plane with the slot in the nut. Vehicles without pins and castles use locknuts.

The cotter pin should fit in the slots of the nut. Try some extra washers or look for a thicker nut. Your other choice would be to use crimped type nuts that are like the factory nuts.

I agree, use a flat washer.
