By the sound of it, the wheel, the tyre, or possibly a suspension component has been damaged somewhat in the impact.

If the tyre, then it could have had a chunk taken out of it in the impact, making it out of balance. Or it could have been hit so hard that it's now mis-shapen.

If the wheel, again, it may have been knocked out of shape.

If the suspension, then most likely a bent arm, less likely damage to shock / spring.

Whichever, it definitely needs looking at ASAP. As it stands, it could suffer a catastrophic failure at any time while driving - not something you want to happen on a motorway.

As a first suggestion, take it into an independent tyre fitting place (not one of the chains, as soon as they see a woman the price doubles), mention what the symptoms are, and they'll get it up in the air and have a look at it.

Yes indeed-this needs checking,if only for piece of mind.

Start SIMPLE.The first thing i would do would be to jack the car up at home--get a friend to help if necessary. Is there anything visibly stuck up there?-in which case carefully remove. Alternatively get a local friendly garage to put it on the ramps and have a good look round.

A few months ago I ran over a small branch that got entangled around the the inside of the front wheel. Once removed all was fine. A few years a similar thing happened when some gravel got stuck in a brake disc. The garage spotted and removed it!

In both instances they caused the most horrendous alarming noises, very similar to your wump wump wump+( something stuck, as wheel revolves) . Noise travels-big time.

If you cant see anything obvious--it is then and only then i would book the car in for a thorough diagnostic .....Let this column know the outcome,I am interested.

Aha !...I thought it would be something simple/straighforward!...this very day I drove off from a car park and heard odd sounds underneath.Sure enough though--once i had gone round a couple of bends and driven for 20 mins at 40/50mph there was the sudden sound of a stone/piece of wood freeing itself-then silence! ....so stuff does get stuck sometimes!

I agree that changing the tyres was a good idea. For your interest on my Audi A3 I changed all four last summer for £315. For ultra piece of mind-why not do the rear tyres too once you have given it thought?. It's not just the treads that need looking at--it's the side walls that can so easily deteriorate and even get damaged after 3 years.
