Hi
Time for my stupid question of the week..........

Looking at replacing the axle boots on Bella (little leak on one). Couple of questions as there are two types available, rubber and rubber and metal bushing.
Can I easily find which I need without removing the shaft?
Does it matter which one I replace them with?
Is the metal bushing type better if it can be used (I would presume so?)
Did we indeed evolve from apes?
Cheers
