I was driving along and I noticed some whirring and I narrowed it down to the O/S wheel bearing. I changed the rear one a while back and it was pretty easy, so I ordered a new assembly for the front.

When I took it all apart, I didn't realise you have to pull out the old assembly and press the new one in. It's kinda weird because I thought the reason for buying the assembly was so you didn't have to press the bearing out of it haha! Seems kinda weird to press and pull an entire assembly

I saw a bearing pull/press kit on ebay, but its veryyyy expensive (£451.91), I bought the car for £600. I had a couple of questions:

1. Is it possible to pull it using a generic puller? (and press using a generic kit)? I understand there are some clips which snap on removal, so I didn't want to try and pull it without being able to press the new one it. I saw a video on YouTube of a guy bashing one out with a hammer, but it didn't look like a great experience.

2. What is a good price for a second-hand wheel bearing hub? (The bearing and the surrounding hub). I can't see any on ebay, but I was offered one for £100 from a scrapyard.

It's a 2006 454 1.5L

Thanks in advance

You really do need to use the specialist Laser tool for doing the front roller bearing
removal and fit of the new one as it makes doing the job both quick and fairly
easy (assuming you have the right size rather big ring spanner AND a decent/large
sized bench vice to hold the hub assembly in.
ALWAYS buy and fit SKF bearings...that is a definite, as they are the best.
The new caged roller bearing has to be fitted exactly, which is where that
Laser Tools bit of kit comes into its own.
IF the fragile cage of the new bearing is or gets damaged then you cannot
straighten it/fix it, and all you will have then is a heavy paperweight.
Oh and you have to use adequate and appropriate lubricants that have to be
used on the threaded 'force screws' and the thrust bearing of the tool.
(Laser Tools recommend Molybdenum Disulphide Grease [black drive shaft grease])

There is a Laser Tool for sale on ebay.co.uk at the moment...item #167259231857
£369.75  with free delivery.

As for buying a secondhand hub...from a vehicle with unknown age and mileage...
that's a bit like 'Russian Roulette' !

Is there no HobbyGarage/RentalGarage where you can use a hydraulic press? Or you want avoid to remove the hub?

Changed my too, unfortuntely done only a photo from the new studs, but you can see them when installed the brake.

Yes there are, but I was hesitant because I was told there is a high risk of damage with the proper tool.

Thanks for the info!
Unfortunately it's a bit out of budget for a tool I will probably never use again. It's probably worth half of the cars value haha!
At least I know to avoid trying to press it out myself, that's all I really wanted to know

I'll and find a complete hub with bearing. Does the hub have a model number?
I found A4543300220, but im not sure if its the whole hub
