I've just had that problem with my (new) mirrors. More of a problem than I thought as the camper actually goes faster than I expected.
Remove them with a large Philips (not pozi) screwdriver, and tighten the nut behind with a 10mm spanner. There is plenty of play in them.
I think the double strut-leg-arm-brace are for wide bodied, pick-up or Synchro's, though I noticed on the "Modded" forum that Corrado mirrors are the way to go for that "street" (aka aerodynamic) look.
Fitting the big electric mirrors does the job, even at 140kmh they dont budge , problem with the standard mirros is the fact thier flat, and even if you crank the 10mm lock nut up when at high speed and a average head wind anything flat is gonna move!
if you take the 10mm nut off, and the spring ( carefull theres a spr............................................ing , now wheres that gone ) pull the ball from the socket, and "rough" the ball part up with coarse sand paper it grips better....DO NOT over tightten it when you put it back together...
I got myself a large phillips screwdriver that fits the oversize screws so whenever the mirrors get loose I can tighten them wherever I happen to be (as I have to push them in to get on the drive and over time they get slacker.
Hi there, had the same problem, what I did to save the life of the threaded stud behing the mirror in the base, get about 5 or 6 m8 washers and insert them between the spring and the nut, that way there is no danger of overtightening the nut and stripping thte thread, hope this helps.
having recently become pc savvy, it's cool to know that there are some people out there willing to help, working a 72hr week(6 x 12hr nights) can severely restrict access to anything that is open during the day(sleep-please)! so as a relative newbie, getting a good vibe out of you lot, stay cool!!
Well well, just by tightening the nut inside (and borrowing Geoff Capes to move them into position again) looks like the mirrors are now rock-steady. Well, the passenger side one at least.
