Fitting Hubs

[d2dave]

Putting new rear axles in the D2.

I was going to grease the splines to stop them seizing, but decided to check RAVE to see what is suggested.

It says to put a 3mm bead of 640 Locktite around the start of the spline which will then push the Locktite along the spline when fitting hub.

Anyone know the reason for this? I can only see 2 reasons. 1/ to prevent oil leaking down the spline. 2/ To prevent spline wear from a minute bit of back lash on the spline,
due to it being a push fit, not a press fit.

Anyone not used Locktite doing this, or used something else?

There is better stuff than Loctite to prevent oil leaking. With 490Nm of torque on the drive shaft nut I can't see any slippage. Still I bought the Loctite to do my rear hub.

So you reckon that RAVE's reason is purely for stopping oil leaking down spline?

It will also stop the splines fretting.

It'll be this ^ to stop fretting corrosion.
The same reason you either grease the splines every 10-20,000km on the Tdi through Tdci Deefers or run oil lubed hubs.

So what do you suggest I use on my D2?

I shopped around this morning and the only Locktite 640 I could get was a 250 Ml bottle for a bit over $400.

I have a 50 mm bottle coming from OS but this will not arrive until mid June.

Would it be ok to just use grease and then when I get the Locktite I remove clean and apply?

It's available in Victoria, $22 for 50ml.

Should have it in a week

Looking at the shape of the drive shaft where it meets the hub, nice flat surfaces with all that torque holding it together, it will be oil proof.

RAVE says 640. Had a look at 648 specs. It is very similar to 640 with one problem. It cures in 3 minutes, where as 640 has hours.

Rave says that the hub nut has to be tensioned before it cures.

I followed this advice and did not use any Loctite. Just a slight slight smear of anti sieze or grease.

Hub nut - why is it so tight? (https://www.aulro.com/afvb/discovery-2-a/214774-hub-nut-why-so-tight-post3002550.html#post3002550)

Im pretty sure JC follows this practice as well. Will update if I can find the post.

I have replaced both rear hubs, tightened the hub it to spec and staked it. No problems in thousand of km.

Found the post!

Just use ant sieze NOT Loctite:

Loctite Sleeve Retainer 640 - axle shafts into hubs (https://www.aulro.com/afvb/discovery-2-a/181285-loctite-sleeve-retainer-640-axle-shafts-into-hubs-2.html)

There was a revision.

Bulletin No : 0001
CDS. ref: L8431bu Range Rover
Discovery Series II Issue: 2
Date: 26.04.2000
AFFECTED RANGE:
All Range Rover up to VIN: YA 434637 YA 435750
All Discovery II (System 2) up to VIN: Introduced at Job 1 YA 260194
All Discovery II (System 1) in VIN range: Introduced at XA 900000 to XA
907212

PROBLEM:
CLICKING NOISE FROM REAR AXLE
When pulling away from rest in either direction, a clicking noise may be
heard from the rear of the vehicle.
CAUSE:
Excessive spline movement on either:
a) The rear axle shaft to hub spline, (Range Rover).
b) The rear differential flange to pinion spline, (Range Rover and Discovery II).
ACTION:
At the above VINs, the application of Loctite to the above spline locations was introduced during manufacture.
· In case of customer complaint on a vehicle within the affected range,
apply Loctite 648 to the axle shaft or pinion spline as detailed below.
NOTE: Loctite 640, previously specified on Issue I of this bulletin, has been cancelled for use on vehicles in service due to its extended cure time.
· When reassembling rear hubs or rear diff flanges for any other reason, regardless of VIN, apply Loctite 648 to splines as detailed below.
NOTE:Loctite has been applied to Discovery II rear hub splines since the
introduction of the model. Should a Discovery II rear hub be dismantled for any reason, regardless of VIN, Loctite 648 should be used on reassembly as detailed below.

Cheers

And I've followed RAVE and bought Loctite 640!
However it states that " Fixturing time on steel is 2h." I'll leave it for 2 hours

To be perfectly honest, I wouldn't be particularly worried either way, Loctite or not!!

At this point in time I am going to use copper grease. I have 640 on order for when I next dismantle.

As I have only replaced one hub I am sure the rest will need doing at a later date.
