Hi was it easy to do as I need to replace the outer bearing on the rear wheel and one on the front
Probably best to do both in pairs Richard, do it once then you can rest easy.
If you've never done them the specialist tools you see in the video aren't an absolute neccessity.
Axle out, shield out and you'll see the bearings. Lay the wheel on its side. With a drift and a hammer or mallet punch out the bearing from the opposite side.
What is important is when you're driving the new ones in you can either use studding, nuts and washers and pull them in or...drive them in square,,,very important, square..with a socket a tiny bit smaller than the outside diameter of the bearing.
Only allow the socket or whatever to impact on the outer ring of the bearing...absolutely NOT the seal or the inner ring...this would likely jar the race and cause damage...usually accompanied by a knock or stiffness.
As you start to drive them in....keep checking to see they're going in square. If it's not, tap it back out and start again...or look for the hight point and tap it there to level it up, don't keep driving it in not level, you'll risk damaging the hub shell .
