Is it better to use a flat washer under a split washer in most cases?
This camber rod came only with split washers, the ends of the bolt sleeves were chewed up by the spilt washers. I had to file down the roughness a little bit.



Also, is it ok to use a split washer with a flange nut or bolt? Or is it overkill?

 

I always use a flat washer under a lock washer to protect the subsurface.

 

Recommend using blue 243 threadlocker. 243 is oil resistant compared to the 242.

Working as a mechanical engineer at my last job, we moved away from split lockwashers and used liquid threadlocker.

Doesn’t hurt to use both threadlocker with the split lock washer.

 

To answer the question, a split washer is to be used with a flat washer always. They come as a pair.

Suggestion....a FLANGED self locking nut will serve the same purpose

 

Thanks for the tip, I will be using anti-seize lubricant on all of the nuts and bolts!
Does a drop of threadlocker 243 over anti-seize lubricant work?

 

anti-seize would most likely kill the thread-locker. On high vibration suspension bolts you want to use thread-locker, not anti-seize.

 

As I disassembled my engine and exhaust systems I snapped off quite a few fasteners that I tightened in 2007.

I had to reorder a racing beat pre-silencer because the welded studs on it were too corroded to reuse!

Going forward with my restoration (not quite stock), I feel the obligation to make any future disassembly easier and less destructive to all the parts involved.

So, anti-seize lubricant will be used on all the parts!

My concern with parts becoming loose over time using anti-seize lubricant will be addressed using the proper torquing of all the fasteners.

Thanks for the posts!

 

I'm just a DIYer, but I've seen someone who works on Toyota Land Cruisers professionally claim that threadlocker can prevent corrosion or galling since it coats the metals. It might not be as effective as anti-seize, but I would rather deal with replacing a rusted fastener than experience any suspension part coming loose or falling off of the car while it is moving.
