Hey, i just tackled this a few weeks ago. I had trouble finding the parts. Thank God for the forum.
The removal was easy.
The install was not bad either. Most people press them in. I just used a dead blow hammer and pushed the top rim into the knuckle then worked my way around the back of seal with the hammer. Went right in... no issues.
Good luck. Whenever i do these types of repairs I always feel like i wrestled a bear all weekend. But it beats the dealer and the mechanic.
