OK everyone, I have an 05 G35; i also posed the question on G35driver. Now, when I lift the car off the ground, the drivers rear wheel has play on the vertical plane (the lug nuts were NOT loosened) but the passenger rear wheel does not do the same. Doing a quick google search, it sounds like the bearings on the drivers rear wheel are shot; obviously, I'm going to replace them.

The question I have is:
A) do I absolutely need to replace the hub as well
B) assuming I need to replace the bearings and hub, should I do both at the same time, or can I replace one side at a time (in other words, is the failure rate equal on both sides, or do they fail independent of each other)

C) on a scale of 1-10, how difficult is this as a DIY? I've done my own Vortech installation, as well as BBK on all 4 corners

D) I called a local tuner shop, and they said that OEM vs aftermarket hubs and bearings don't really have any significant difference in quality; is there any truth to this?

Sorry if this was in the wrong forum; i browsed the technical section and found this the most appropriate for the topic.

Thanks in advance
John

 

You just need to get a bearing from your local autozone/O'reillys. They sell timken bearings for like $70 and they come with lifetime warranties. Just have the bearing pressed onto your current hub.

It's a super easy job with the right tools.

Here's a quick list I'll make off top of my head (may be forgetting things)

1. Take wheels and brake calipers off
2. Take rotor off (you'll need a rubber mallet)
3. Take cotter pin out of axle
4. Take the big axle nut off
5. Tap the end of the axle with a mallet a few times
6. Now go on backside of hub
7. You'll have access to all of the bolts behind the hub without having to remove the axles.
8. Pull bearing / hub out
9. You can do the rest


Good luck.

 

AH, OK. I'll go this route. Should I replace hubs as well, or not necessarily?

My car only has 48K miles on it

 

I think you'd be fine to re use your current hubs. That's what I did at least. My 08 has 67k.

 

Just replace the one. It's usually a pothole, unbalanced wheel, un even tire wear (ware?lol) uneven tire pressure. Reusing the hub is fine.
