    Hi,

    Further to my recent post. I have a question...?

    We had a tow bar fitted to our Sprinter Based motorhome a few days ago. I drove the motorhome to the installer 35 miles from our home, no problems.

    When the tow bar fitters had installed the Type Approved bar, they had to make several adjustments to the supplied equipment. So it took some time and modifications.

    Upon driving away, the van seems to be vibrating. Not violently, but as if you were driving on very fine rumble strips or one of those Belgian concrete motorways.

    I can't imagine how fitting a tow bar could change the way the van feels to drive. Or how they could of done something to alter things?.

    Before I contact them and sound stupid. I wonder if anyone had any thoughts on the matter please?

    sounds like the exhaust is rubbing against the metal of the towbar.
    quite common fault....... needs tweeking.

    There is certainly something a bit amiss, so don't feel bad about taking it back, as the longer you leave it the quicker it could do some damage.

    I understand your thinking on some white man van`s..... but don`t most if not all MoHo exhaust`s come out near the front.. ??

    If so why would they have to interfere with the exhaust..??

    Or have I got it wrong........... as usual... :(;)

    Exhaust would be my guess too, assuming it goes near the tow bar, it happened on a vehicle of mine. But just check all the wheel nuts are tight before you next move the vehicle. They may have taken the wheels off to gain access and not tightened them!

    Hi Trev,

    Like others, I'd be suspecting the exhaust and getting myself underneath to check out the possibility. It may be a hand brake cable vibrating against the framework, causing resonance, but if not found, as advised above, check the wheel nuts before taking the MH back to the fitters.

    Good luck with it. (y)

    Jock.

    That's a good point mo.....
    Just thinking it's nearly the only thing it could be ( assuming it comes out the rear of the vehicle)

    I would think exhaust would only 'rattle' not vibrate------most likely cause (most simple) would be wheel nuts loose--or wheel not centred/seating correctly.
    Alternative cause could be serious:(------get it sorted ASAP--or sooner

    sounds like wheel nuts or the wheel balance has gone out did they remove the wheels they might have knocked ono of the balance weights off

    I'd be checking the wheel nuts are all tight.
    Also - check one or more of the wheel balance weights haven't been knocked off

    Hi, My apologies, I have been busy and poorly for a few days and the MH is outside, not moved. Not had chance to mail them yet. I am going to do it over the weekend.

    Thanks Folks......

    Hi All,

    After several attempts to contact the company in question by email, ebay and telephone, we eventually spoke with them yesterday.

    They are adamant that the fitment of one of their tow bars could cause such an issue. Despite explaining that immediately after fitting the issue started.

    I have politely suggested that they may like the opportunity to at least look at the vehicle before I go anywhere else for an opinion and I it was again pointed out to me that the tow bar could not be causing the problem. So far, they have not offered any date where they are willing to inspect the work, that and distance being a problem as we both work.

    Not sure where to go from here at the moment. Very peed off. I do not understand why companies fail to respond to multi attempts for contact.

    Bearing in mind the distance to the towbar fitters and the feedback from others regarding tyre and wheel potential suspects, would it be worth popping into your local tyre depot first?
