A week or two ago someone was talking about the nut on the top of the
kingpin causing the upper trunion to lock the swivel. I took my front end
apart today to replace the lower A arm rubber bushings and have the A arm on
my bench. I am sure I have replacement kingpins and have run into the same
issue. They way they are made there is no way to shim up the upper trunion
so that it won't lock down the upper trunion swivel. It looks like the
threaded part of the king pin is threaded down too far so that no amount of
shims could possibly fix it. It was supplied with a nyloc so I am assuming
that the procedure would be to just crank it down snug. I think I will
drill the top of the kingpin and use a castle nut set just so there is not
up/down play and put a cotter pin in it or maybe use a nut and a lock nut.
The latter may be a better idea as it could be adjusted as the thrust washer
wears. Am I missing something?
The PO of my car had put the lower fulcrum pins in backwards which allowed
them to move around. I drove the car 400 miles last weekend with them that
way and didn't notice until I got home. Lucky I didn't have a bigger
problem but the car ran great at 70! Also glad I had a spare set of fulcrum
pins as the old metal sleeve had seized solid to the pins. I am about to
put it back together and will put some anti seize on the pins.
