Need 88 Skyline Diff/bearing Diagram

[klrbro]

Hi,

Got a bit of a prob, rear passanger side bearing disintegrated, with it the seal, and apparently there's a spacer that goes b/w the bearing and the cover that holds the whole thing together

Can someone supply me with a diagram of how this thing is meant to be put together?

BTW, I'm in PNG, so going down to the wreckers is not an option

Cheers

KB,

Is it an Oz delivered 4 door R31 with a live axle or imported with IRS?

Cheers, D

[klrbro]

Whoa,

It's got a RB30 motor, EFI etc. Purchased in Melbourne, as far as I've been told, manufactured in Japan with the diff being the only aussie component. It's a beatiful (and a little rusty) stationwagon

Cheers

In that case it's probably a local R31 with a live axle.

I guess the bearing your talking about is out on the end near the wheel eh!

If this is the case, the bearing you're talking about is just behind the axle mount flange. Correct?????

Cheers, D

fairly sure every thing, ie retainer, bearing and seal comes in kit, and goes in that order, thats if solid rear

[Ghostrider]

Yeah! That's right as the manual suggests.

Just need to confirm what it is.

C'mon guys, some of the R31 owners should be all over this?

Cheers, D

Or a Falcodore owner? It's a BW diff afterall!

And remember, it's a retainer, ie it retains the bearing on the shaft. More importantly, it retains the whole axle in the housing, preventing it (and your wheel) parting company with the car. Don't just bash the retainer on with a hammer. I'm inclined to think that if you need to ask questions on an internet forum, you probably should get someone more experienced to fit the bearings for you.

Hi Guys,

Thanks for your input, but I really need the part numbers or a diagram (even Better) for the passanger side bearing/retainer/seal wheel assembly for a '88 nissan skyline/stationwagon, VIN: WCJR31FGX3

Thanks

Nick

yea if aus r31 will b bw78 diff. will need 2 drop ur centre out and press off the old bearing. then just go 2 a bearing joint and match it up (dunno what auto places u have there?). just normal taper roller/plain bearing or something (cnt remember) nothing special. press new 1 back on and this ring ur talkin about is ur shim, it sets the backlash between the pinion and crown gear. goes between the bearing and diff housing will def need it.

should b pretty straight forward taking it out when looking at it.

take wheels off, slide disks off (floating rear), undo 4 bolt axle flanges, pull axles out, undo diff plate, undo 4 bolts on the bearing cups. then diff centre should just fall out, might have 2 jimmy it out with large screw driver etc...

close-ish just dw about the mini spool part. more stuff on that site\/

We've got the bearing out, that's not a prob, but my mechanic recons there should have been a spacer holding the bearing in place. and we need the part numbers for the spacer/retainer and the seal

The old bearing was in bits and pieces when we took the cover and axel out...

What is it about people posting tech how-to articles and them filling them with crappy mobile phone photos? Even the most basic phone takes half decent pics now, and digi cameras aren't that dear (my son's $70 job takes fantastic photos). Sorry for the rant but I take tech photos and write tech reports for a living and this kind of thing just sh!ts me no end.

Now that's out of my system, I have a Nissan Service Manual, and there are no pics in there showing the rear axle installation. It does, however mention the bearing retainer ring which goes on the inboard side of the bearing. Note this ring is never to be reused, and a new one will be supplied with the bearing kit. Your mechanic is correct - there should have been one. don't fret if you can't find it, as a new one will be supplied (as long as it's not floaring in your axle housing somewhere )

The photo below shows a Mazda RX2 setup, which uses the same concept as all live axle setups AFAIK. note that the locking collar has been welded to the axle in the photo - not what I'd call good practice, but it's how I got the car. Apparently it was a common fix for early Falcon (c1970's) when the rear axles used to pull out whilst driving.
