clunking gears

[burgerman]

Hi all, Just had wifeys 90  back from the garage, it had the disco 2 gears fitted to upgrade the gearing, Must admit it makes a huge amount of difference, But on changing gear and on/off throttle it clunks, kinda like backlash type of noise??  
 Any how as  i know nowt at all about gearboxes  am  i right to say it should not do it now ? as it was sweet as a nutty thing when it went in,

  Not spoken to the garage yet till after crimbo,

I will not name the garage till they have had the chance to check it out, But i will say it was NOT ashcrofts,

i bet you are hearing a slight back lash from the rear diff or possibly a bit of play now being felt from your prop on the rear as the hardy spicer joint might be on the way out
