I have a problem with my motorhome that i am having trouble identifying.
When i take up drive from a standing start and change gear i get a single knock from front offside, sounds to me like its a C/V joint but they are only
2000 miles old. Both side C/V joints feel like they have the same amount of play in them.
Any ideas welcomed as not sure where to look now

engine mounts gearbox mounts

Mcpherson strut?
Maybe packing up or Strut Base....

When you say the CV joints are only 2,000 miles old do you mean the motorhome itself has only covered 2,000 miles or the CV joints were replaced 2,000 miles ago?

If the CV joints were replaced and the motorhome itself has covered higher mileage then I'd be suspecting other suspension parts or indeed engine/transmission mounts. If worn they can all move and produce a knock sound coming on/off load.
