Front Suspension Too Tight?

[TR3driver]

One of them has 4 holes cut in the plate to fit on the studs for the shock mounts in the bottom of the spring pan. I quite like this style and it works very well.

Me too.

Thanks again for all the help. Slowly, this resto is getting done...

Pat- reviving this thread here (and Randall, feel free to contribute).

your photo shows the lower/inner fulcrum pin with the supplied nyloc nuts. I have the exact same set-up on my restored front end.

however recently, a "car guy" (non LBC), came over to my garage (and saw my chassis) and told me he thought it looked dangerous - that the ends of the threaded fulcrum pins were "only" flush with the nyloc nut. Which if you look closely at your photo (and my newly assembled front end as well), is the situation I see in your photo (the fulcrum pin end is flush with the nut face).

Is it OKAY that there is not additional threaded end (of the fulcrum pin) protruding beyond the nyloc nut face?

I thought I might have read somewhere before that the nyloc nuts supplied in the kits by Moss where too thick. I could be wrong.

thanks for any advisory, wes.

Your "car guy" is exactly right, Wes. I had to zoom way in to see what you are talking about, but Pat's photo does show nuts that are too tall in my opinion.

Nyloc nuts have a nylon insert that is supposed to deform and grip the threads to keep the nut from coming loose with vibration, etc. But the last thread at the tip of the fulcrum pin is not full diameter and so may not deform the nylon enough to get a good grip. You need a nut that lets at least part of the thread protrude beyond the nut, otherwise it may come loose in service and fall off.

One easy solution is to clean the threads with solvent and use a drop of Loctite.

Can someone refresh my memory, are those inner/lower pins drilled with holes for a cotter pin?

the reason I ask is that I also thought a solution to be to drill and wire the nut with safety wire.

I don't believe they were originally drilled. Outer and upper pins yes, but not the lower inner.

Might not be too hard to drill them, but you'll probably have to remove the suspension to get enough room for the drill motor. I don't think there's enough room for even a right angle adapter (although a cable drive might work).

Short Nylocs are available from MMC, or you can just grind off the bottom of a standard one (being careful not to get it hot enough to melt the nylon).

I think that I'm just going to go-out and find "thinner" versions of the same nyloc nuts and use them in place of the "thicker" ones currently installed.

Does anyone recall the proper size nuts? Are those 1/2" UNF or are those larger than that?

I tried to drill mine, but broke 3 bits before I gave up. They are apparently hardened steel...
