Bumpy ride (no knocking)

Hi I seem to be feeling all small bumps , like small tiny potholes , tarmac joins in rd it really sends a shock through the cabin but bigger rounded bumps all fine and normal flat rds seem to glide over , shoujd these cars feel smooth on general rds etc , my suspension goes up and down as should , is there any components I should check ?

Good morning,

Is this vehicle new to you? The first thing I would do is check all the tyre pressures. I noticed once before when I put the maximum values in the ride seems harsh as you describe (I think my old tyre pump was faulty). I have a new Milwaulkee battery pump, and things seem okay now. Straightforward to check before you go digging further perhaps?

Thumbs Up

Just drop maybe 2 psi off all around and see if you notice a difference. You can decide how to set it up from there Cool

Check the suspension bushes if previous owner has fitted none standard or Poly bushes that's your problem.
 It can when others can't,
It will when others won't,
It goes where others don't.
