The time has come to replace my wheel hub assemblies. The Land Rover manual says to use STC 50554 sealant on the driveshaft splines on reassembly. Apparently an equivalent of this sealant is Loctite 648 retaining compound. My concern is removing the hubs in the future. It sounds like Loctite 648 is almost considered permenant, requiring high heat and a press for disassembly.

Anyone ever used Loctite 648 on their hub splines and then later taken it back off? Any thoughts on this issue?

 

I just used Permatex 80078 Anti-Seize Lubricant on the splines when I replaced one of my front hubs 10 years and 80K miles ago.
I have had no problems.

 

I used Blue thread locker. If you search long enough there is a thread that has an equivalent of what RAVE calls for, and I believe the whole point is that is is permanent. The stuff that was on my original hubs was definitely meant to be permanent. I did not find that thread in time.

The Hubs are torqued on there so tight, and the sealant must just make sure there is no wiggle room. I don't feel like my hub is in any danger of coming off anytime soon.

 

Used silver anti-seize on my 01...like I have on the hundreds of hubs I've done in the past. Why anyone would want to put lock tight on the splines would be beyond me. The last thing you want...is to have to beat your brains out...getting that shaft out of there. You're really taking a chance at messing up the threads and axle shaft, in my opinion, if you use lock-tight of any type. The torque value is great enough that you will never, ever have to worry about it coming loose.

I didn't put anything at all. No issue in 20k mikes.

 

Your screwed...

 

Here is the info I found in the RAVE and service bulletins.The bulletins indicate to use 648 (as opposed to 640. Also I wonder why the torque specs in the two attached documents is do different (360 ft/lbs in RAVE vs. 250 ft/lbs in the bulletin)?

Bulletin N o : 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.

 

I got mine off Amazon. Hope the link works

Care to elaborate?
