So today was a successful day.
After a lot of hammering a chisel around the edges between the bearing and steering knuckle, then putting anti-seize in the same areas.
Then repeated the same sequence again, i finally got the bearing separated from the knuckle.
I gave the steering knuckle face a bit of a clean, the best i could with my bashed in hand from the 5lb lump hammer.
I then hydraulic pressed the new bearing together with the wheel hub.
After a bit of jiggery pokery i got the bearing and hub back on the steering knuckle.
Got my wheel back on and drove home
Having had a dodgy bearing for quite a while and sounding like i was being followed by a chinook whilst driving.
I forgot how quiet it was to drive my car apart from the grumble of my diesel lump, it was bliss.
Now that annoying problem is sorted, i need to save my pennies for a remap and some new wheels from my to do list.
