rear wheel bearing

[Gelbster]

Meir,
You seem to be getting deeper into the mechanical bowels of the Boxster with each post !Well done and thanks for sharing.
So let me anticipate one of your future posts and suggest a better puller ?
Eventually you are going to need to replace a bearing and maybe 2nd gear in the 6 speed gearbox. For that you need a puller that coincidentally would work on the hub but is also about the only one that fits for the gearbox.It is a Kukko slender arm puller KK 20-10-S

A cheaper alternative that may work is:
12 PC New Car Repair Tools Universal Puller Set Two Arms Pulley Remover N008341 | eBay
The 'dremel-tool' technique mentioned earlier certainly works but requires great care.
When fitting the new bearing, remember the freezer/oven technique to avoid damage.
Are you doing the CV boots also?
Keep us posted.

thank you very much Gelbster.
added the tool to my wish list.
bearing are seating in the freezer for few days now
i rebuilt the axles (boots and joints) about 15k miles ago, and they still look good.
i hope to finish it tomorrow, and find the time to make a nice write up.
i was very surprised to see that there is no instructions or videos online for this procedure, using the SIR tool.
its very easy once you figure it out, but it is some what of a jigsaw Puzzle.

Hello guys.
due to lack of time, i never got around to update this thread, and do the write-up as i wanted to.
i will try to add some pictures and explanation to the thread, and maybe one day will find the time to make a PDF document of the full procedure.

[Meir]

the first step after removing the axle, is to remove the hub.
use the SIR tool as described in page #1 in the manual.



i know that some succeeded in installing the "horseshoe" part without removing the e-brake pads. didn't work for me.

this is the setup from the front.



and from the back



when the hub comes out, the bearing will brake apart and the inner race will stay on the bearing.



the hub has to grooves in it, that will allow you to insert the hands of the bearing puller, as described in earlier posts in this thread.
once removing the inner race of the bearing from the hubs, i placed the hubs in the freezer.

[Meir]

this is how it looks with the hub removed.



remove the 4 screws and the retaining plate, and continue to bearing removal.

this is the setup of the tool for bearing removal.



this is to illustrate the order of the parts with relation to the bearing. picture was taken after the bereang was already
removed.



this is how the setup looks from the front



and from the back




VERY IMPORTANT! make sure all parts of the tool are perfectly aligned with the outer and inner races of the bearing respectively, before you start wrenching. not easy when you need to hold all the parts and wrench on both sides. the tool is also pretty heavy.
if you have someone who can help you, that will be great. this is one of these projects where another set of hands is a bless.

this is the setup for installing the new bearing.



the setup of the tool is very similar to the removing setup, but part #14 is replaced by the installation washer and the orientation of the tool is reversed.
this is how it looks from the front



and this is from the back



before i started wrenching, i made sure the bearing is totally squarer with the bearing housing.
i took the bearing out of the freezer and lightly taped it with a rubber mallet, before i put the tool over it, so basically the bearing was slightly inserted, and hanging by itself in the housing.



i made sure the plate is touching the housing, and the bearing is totally inserted and flush with the surface.

[Meir]

after having the first bearing in, that was the point i made a horrible mistake.
the next step after inserting the bearing should be to reinstall the retaining plate. i forgot to do that, and continued with installing the hub.
i ended up repeating the whole process from the beginning
removing the hub, removing the inner race from the hub and removing the bearing from the housing.
boy. that was a long day.
obviously, i also needed a new bearing.
lucky for me, i live 2 minutes drive from tuneRS (literally)so i gave the call.
they didn't have the bearing in hand, but was kind enough to order it for me.
the guy gave me a call in about an hour, and i picked it up.
so its good opportunity to thank the guys at tuneRS, for saving me the trip to the stealership.
