I have a v3 type r with leda coilovers, 22mm adjustable white line arb set in middle position and alloy solid drop links with poly bushes.

The problem I am having is that the top bolts that connect the arb to the drop links are coming loose. I have tightened them up now 3 times and damn tight too but they still come loose. The bottom bolts are fine.

So, I have the bolt coming from the drop link side fitted with a washer and the threaded side coming though the arb has just the nut, as per how they were fitted when uses oe links.

Should it have washers both sides?

 

Washer and some of those nylock nuts should help.

 

That's what I'm thinking. I just wanted to know if if was a common problem with aftermarket drop links, although it never happened on my last classic.

 

I've had to tighten up my fronts a few times

 

Double nutted them and they are now fine. If I get round to it I may add washers too. Cheers for the advice.

 

Nylocs are best.
Because the bush flexes and the arb rotates around the drop link bolt it has the effect of loosening the nut. So a good nyloc or locking nut is required.
A regular M8 will just work loose.
I lost the rear offside nut bolt and bush shortly after replacing all fixings with stainless steel items. Nylocs on there now though.

 

Would a bit of threadlock not have the same effect?
