Rear disc

[thebandit92]

Hi everyone,not been on here in a long time as i bought a Sprinter a couple years ago.Had nothing but trouble so gone back to a Transit jumbo,forgot how small they are compared to Sprinter.
Anyway,bought a 10 plate jumbo and just changing rear discs.Already done passenger side but not changed the 65 mm hub nut and not torqed it up as no torque wrench.Just wondering how important it is to put a new nut on and torque it,am i gonna have problems at some point if i don't.

Thanks for any advice.
