Unscrewing Screws and wheel balance
Unscrewing Screws and wheel balance

I see that there is a recent post about unscrewing screws. I have had similar experiences with finding screws appearing in odd places and not accounting for where they have come from, as well as having to re tighten several that have worked lose. We have experienced problems with the cupboard doors and have Automotive Leisure apply warranty fix with the plate along the bottom rim of the cupboards (not a complete success as the hinges on the doors are no working lose).
I got into conversation with a Dutch Eriba owner on a Campsite near Quenca. He informs me that he had similar problems and while researching the solutions discovered that the Wheels on the Eriba’s are not balanced. He informed me that he had both his wheels balanced (I think he said it required in the region of 170 gramms per wheel ) and from that point on he has eliminated the vibration caused by the previously unbalanced wheels and no longer experience’s loose screws!
Has anybody else experienced this as a solution to what appears to be a persistent problem with our much loved vans????

My own experience of balancing caravan wheels is that tyre fitters won't necessarily balance them as a matter of course in the way they do car wheels, though I reckon they should.
The thing is that an unbalanced caravan wheel will vibrate in exactly the same way that an unbalanced car wheel will; it's just that you can't feel it.
And it's perfectly reasonable to expect vibration to be a contributing factor in stuff working loose and falling on the floor.
The other thing that doesn't help - and it's one you can't really do much about - is that caravan suspension is pretty rudimentary and certainly nowhere near as compliant as car suspension is. The obvious result of this is that the ride is pants and the shock of every bump and pothole is transmitted into the body relatively unmolested. Having tyres blown up too hard also doesn't help as the sidewalls of over-inflated tyres won't flex as much as they should, and I'm pretty sure that the natural flexing of the tyre is a significant component in the caravan's suspension.
There won't be a specific amount of weight required to balance the wheels. If it turns out that it needs 170g each side, you could take some small comfort from the fact that they need the same weight. At least there's some consistency in the manufacture of the tyres (and wheels) if nothing else.
I reckon it makes a ton of sense to have the wheels balanced. If they aren't balanced now - and I appreciate that it's a faff - I'd get it done irrespective of how much life was left in the tyres and I'd certainly make sure that new ones were balanced when they were put on. The cost implications are negligible.

For comparison our 310 is shod with Semperit 165/80R13 83T tyres on 4 1/2J x 13 H2 steel wheels.
The virtually unused spare needed 30g to achieve balance.
The 15-20% used tyres needed 35g and 65g respectively.
None have been patched.
These were statically balanced with a Gunson's Wheelrite which I have used for re-balancing car wheels when necessary through their service life for many years.
170g does sound a lot, but might be due to a vulcanised repair patch, or to putting on lots of mileage on an initially unbalanced wheel.
