Hi everyone i own a vauxhall zafira 1.6 w reg and last week noticed a groining noise which i was told was probably the front offside wheel bearing from where the noise seemed to be coming from.

I ordered a new wheel bearing and put it on myself,the one i took off seemed fine though.It turns out that it is the nearside bearing that is the problem.I tried to put the old offside on but it does not fit?

Are the offside and nearside different?

My Zafira is the non abs type and also does not have the speed sensor.

Also the new wheel bearing needs a larger hub dust cap because my old one is two small?
