If you research spring washers you might come across:

"Helical spring lock washers have been in use for well over 100 years. They are still used on many applications in the belief that they will will "lock" the nut/bolt to the joint and prevent loosening. The body of evidence, based upon both experience and experimental results, is that they do not prevent loosening and can be shown to actually speed up the rate of loosening in many cases. Junker originally showed in his work published in 1969 that these washers are ineffective in preventing loosening. Joints containing these washers have come loose resulting in structural failure leading to both material and human loss."

You'll also come across articles that sing their praises and go to great lengths about how they work as springs etc to take up shockloads and expansion/contraction but just as many saying they only actually work, if at all, because the cut edges dig in to the nut and substrate and discourage turning! 
 

Who knows????!!!!!

#74 - If you drop Martin Phipps an email (Caterham archivist) with your chassis number, he can tell you what the original shipped unit was.  Martin.Phipps@Caterham.com.  He was really helpful when i asked about mine (Ford diff with Titan LSD for me)

Broken spring washers are usually due to being re used - time & time again.

If I remove the long bolt to replace the washer on the other side, is there a risk things will shift and it'll be difficult to get back in?

I would say there is, but you might get away with it. 

That part of the assembly doesn't line up too well and that bolt often (always?) needs a good whack with a hammer to get it through. Having said that it will probably pull back in line using the same method. 

If you remove it the diff will only be supported by the two lower bolts and it could move. As I said, you'd probably get it to go back in line but then you might have disturbed the two front bolts and they should be taken out and refitted! 

I'm not sure I'd go to that length at this stage, just change the nut and the washer at that end and keep an eye on it.

LOL, I meant to post that on my thread here:

https://www.lotus7.club/forum/techtalk/creaksqueak-coming-and-throttle

Luckily I posted it on a diff thread where I still got the advice I needed. Haha!

Thanks chaps.

@ #84

Thank you Dan

I'll drop Martin an email - much appreciated. 

Having gained input from Peter Scott and spoken to Ian at PT Sports Car (where I bought mine from), I'm expecting Martin to confirm that it has a Ford Diff Housing with ZF internals. 

Though based on its age I foresee a winter Diff rebuild for peace of mind. Hence looking forward to following Marks Blog

@ #90 No problem Chris.  I have all sorts of noises and clattering coming from mine (3000 miles but apparently its ok?), so im considering a Tracsport, but ideally i need someone to get in there and make sure that its all adjusted properly first and then take it from there!
