    Hi everyone, I'm looking for a bit of help and a possible warning to others.

    I dirve a 29foot REXHALL VISION based on the Ford 460 Chassis

    I arrived home yesterday after spending the Weekend at ABBEY HILL Steam Fair at Yeovil.

    My route includes the western end of the A303, as I thought I new this road i didn't have the Sat Nav on so the precise location is unknown. All I can say is that it was after the Hairpin bend which was preceeded by a 1/4 mile dual carriageway going up to the disused Filling Station which is about 10 miles from Honiton.

    The road surface along this stretch to say the least is BAD, there are numerous shallow but wide potholes. Anyhow back to the incident . I was travelling about 30mph as I had just slowed down for a slow Carlesberg Delivery Lorry, outside the Derilect garage both front wheels hit the left-hand side of two seperate holes. Both wheels twitched to the right and then the steering proceeded to shake violently so much so I had to come to a complete stop to gain control.

    A few yards futher on I was able to pull into a Lay-by, looking around the RV I couldn't find anything wrong with the steering, however two of my Belly Lockers had burst there catches due to the violent shaking, front left which housed my wifes Mobility chair and rear right which housed a heavy box.

    The Question I want to ask is this, do you think I have a problem with the steering or do you think ( like Me ) that the hitting of two pot holes started a train reaction, it was similar to a Caravan snaking. I have been driving various sizes of vehicles over 44 years and this is the first time this has ever happened.

    One thing I have decided though is to stop using the A303.

    Cheers

    Brian

    I suggest you get your steering and shocks checked.

    Your chassis and running gear should handle bad roads without problem.
    So it sounds like something mechanical at the front end to me.

    i would say, if it was ok after you stopped, it was a gyroscopic effect on the wheels.
    same thing as a "tank slapper" on a motorbike.

    sudden change of direction on a spinning wheel and it will twitch from side to side sometime violently.

    as an example, silly one i know but, hold a bike wheel by the axle and spin it.....try to turn the wheel off its axis.....if it does then it will turn back the other way an equal amount and back again until it looses momentum.

    As 45 e ever sugested have the steering checked. I don't know how bad the pot holes were, but could it have caused some damage to the side wall of a tyre , or caused separation of the tyre cords and or tread? Has a wheel come loose ? You need to check all possibilities.

    agreed Keith, but it would still be doing it now if any damage had been caused....im only assuming it didnt do it anymore after setting off again..but i did state that in my post.:thumb:

    Just my two penneth,, If you can get back and take some photo`s of the pot holes, especially the depth.

    Then if you find that the potholes have caused some damage to your vehicle, you have every right to claim from the Council/County Council in which the potholes are..

    But make sure you have photographic evidence of the bad surface to show them, because once you have complained or put in a claim they will hot foot it and patch them up,,
    Without photo evidence they will deny any liability.

    All councils by law have to have insurance to cover such issues,, the same for pedestrians and broken kerbs/paving stones etc, and tripping up and receiving injury`s to yourself..

    If the public does not bring such issues and claims to the council,, then nothing will get done about the attrocious conditions our road are getting into. :thumb:

    Hi Brian
    exactly the same scenario happened on the M1 with my previous RV also a ford chassis caused by the lorry tram lines in the slow lane I was doing about 60 when this exact phenomenon set its self in motion
    convinced both front wheels were falling off, a thorough check after a 40mph trip home found nothing wrong, the next few journey's were a trifle tense to say the least, it never repeated itself ever again:Eeek: its horrendous when it does happen, as im sure you will agree
    Geo
    PS respect for slowing down for the Carlesburg truck

    Use a film camera.

    Most council's ignore digital evidence.

    Ah, proper tramlines were notorious for that Geo.
    What with narrow, and sometimes beaded edge tyres.

    If you didn't lose control, you ended up at the terminus.

    Especially on a bike.

    Thanks to you ALL for your helpfull advice especialy GEO, your quite correct My wife especialy had an Angina attack but luckily I have all the medication required for such an incident. It didn't help that she had her eyes closed and had dosed off at the time.

    I will also be checking the alignment of the track/wheels etc.
