Only thing time consuming was getting ahold of the parts. Took me about an hour and a half I'd say to completely finish but I found a deal on a hub and bearing so I didn't need a press. My first time doing a bearing on my G too.

 

Ten hours?! No way. I bought my press from Harbor Freight with a coupon that I paid like a dollar for on ebay. Yeah, I bought a coupon. But it made the press only about sixty bucks. Changing two bearings makes that worth it. And then I have the inner bushing on my left lower control arm that needs replacing, and I'll get to use the press again. Definitely beat paying the stealership. And I have the peace of mind of knowing they didn't screw something else up so they could then replace that and charge me for it too. With 230K, it'd be so easy to say this or that needs replacing and then charge me another $250. I freakin hate them.

 

I think my driver side rear bearing needs replaced. I've done both fronts in the last year and I think the rear is starting to go as well. 75,000 miles 2006 G35X. So it sounds like for the rears I just need the bearing and not the hub like I did on the fronts correct?

Also, if anyone in the NE Ohio area has done this before DIY and would be willing to do mine, I'd gladly pay you for your time!

 

Wow 75k? Seems soon, but I guess in Ohio you have salt and stuff on the road that wears stuff out more quickly than here in the south. But yeah I would bet that you don't need hubs. I didn't at all. If the hub needed replacing, I would figure that you'd get some marked vibration in addition to the propeller airplane in the distance noise.

 

Does anyone know what size press is needed? http://www.northerntool.com/shop/too...ct_35090_35090

will this one work?

 

Maybe you could fit a bearing and hub in there to press them together, but I don't think that one will give you enough space vertically to separate the hub and bearing. This is what I got.

Had to use some strategery to get the bearings off the hubs, but putting the new bearing on the hubs was a cinch.

 

ok, I see thanks for the reply. I saw a similar one at Northern Tool. My mechanic quoted $500 for the job with saving the Wheel hub. I saw a Timken bearing assembly at Rock auto for $44. So it looks like its gonna be all me.

Could you describe your strategy of pressing out the old bearing? Obviously a bearing puller won't work as this tears apart the bearing assembly and leaves part of it on the hub.

Nissan pisses me off sometimes.

 

I couldn't figure out how to separate them on the press with the stuff I had, so I used four old rotors I had recently changed out. I used C-clamps to bind one pair (a front and a rear) with the outside sides of the rotors facing (so they would like H's) and then did the same with the other pair. I turned them flat (front rotors on top so there was more space on the bottom) and hung the bearing edges on the top rotors. I found something that fit down in the bearing about the diameter of the splined part of the hub and wailed away with a hammer until that sucker fell out. I couldn't find anything and didn't want to ruin any sockets I had so I ordered this freaking huge washer from Grainger with the exact diameter I needed. Lemme know if you need pics of this wacky setup; or I could draw it in windows' paint program later.

Okay here's a drawing. Crude but I think it shows what I did. I forgot to show the clamps, though, but you can probably guess you'd have to put them through the centers of the rotors and keep the clamp away from the center of the whole setup so that you have the space for hammerin'. Hope this at least gives you some ideas.

Putting the new bearing on the hub with my nifty press took all of 90 seconds, and I was taking it really slowly to make sure I didn't screw anything up.

 

I just replaced the bearing on my G this weekend. In one of the pictures it shows a dust ring, but when I pressed my hub out of the old bearing I didn't see that ring. I had to cut the top portion of the bearing off because it was fused onto the hub, so maybe it was part of that and I didn't notice. When I pressed the new bearing on, I didn't add that ring. Will this cause any issues? I would hate to go through this whole process again for that ring not being there. Thanks

 

The pictures you mention above show the bearing being taken apart in TWO pieces. The same happened to me- when i took the old hub off my car, one piece of the bearing came off with it while the other was rusted solid to the knuckle exposing the packing grease and ***** inside. If you were able to get your bearing off in one piece congrats. There was definitly no dust cover with my assembly.

 

Thanks for the info, that is a relief!! I still have the other rear bearing to go.

 

I have a question..

I bought a rear assembly hub and wheel bearing. I'm going to go have it pressed. Is it necessary to purchase a seal aswell?

Thanks

 

The bearing comes in one piece. There should be nothing you need to do but press it onto the hub.

 

Can someone link me to the coupe bearings for the front and back? I am tired of searching and want to replace these ASAP . I would appreciate something better then OEM quality, but OEM is fine too! Also if there is any necessary grease I should buy let me know that too

 

I chose to drop the spring buckets. You can do it without but it's a big PITA especially if you need to do this in your driveway, and you will probably need a big bar to crack the bolts free on the calipers and the wheel bearings, so the added room is priceless considering how easy it is to drop the spring buckets

Use a jack to support the bucket, remove the one 17mm Head bolt closest to the wheel end, and lower/pry it out as you lower the jack, then remove the spring. If the bushing is tight you can use rope, etc to keep it down and out of the way (as pictured).





At this point you have easy access to pull the CV shafts out safely without tearing the boots, and you have access to get a bar on the wheel bearing and Caliper bolts, which will likely be tighter than heck, especially if you live in a climate like mine!
