3.9 Range Rover rear axle onto defender

Recommended Posts

Gents,

Just been given the offer of a Range Rover 3.9 rear axle (very, very cheap).

I was originally going to convert to a disco rear axle on my 90 (rear drums) but been told the range rover axles should fit.

The RR axle age is unknown but being off a 3.9 must be fairly newish.

The questions:

1) Will this axle fit?

2) Is the diff the same?

3) Are the calipers the same as a disco/defender and hence won't need to bugger about significantly change anything?

Are there any gurus out there who can answer this befor Ralph? :D:D:D

Let the tournament begin.............

Thanks in advance.

Regards

Grant

Yep, the axle will fit. :)

The diff may be a 24spline jobby... pull a halfsaft out and count at the diff end. Dimensionally, the diff is the same. Just plonk the entire axle on and make sure you know what vehicle it is from when buying spare bits like disks

ISTR that the rear calipers are different on pretty much every disk braked Landy.

Sure smoeone will be along with part numbers soon! :lol:

RR rear calipers [NON-ABS] by rear axle serial number -------------------

Upto axle 34S 16421C & 36S 00594B ---- RTC5890 LH & RTC5889 RH

From axle both those serial numbers STC1265 LH & STC 1264 RH

The later part numbers are common to a rear disc braked 90 & ABS fitted RRC :i-m_so_happy:

Should go straight on

remove the byast valve from the front to back on the brakes.

I've got to do this job at some point soon - just a quick check then.... removing the bias valve...

Am I right in assuming I can (simply) fit the axle, and plumb it in using a new brake line without a bias valve?

Does that reflect the cutover from imperial to metric axles?

It will fit as long as it has forward facing shock mounts

I have a 89 RR axle on my 90 and used the same half shafts

Easy to do only problem I had - bloody heavy and the tee pice was imperial for the flexible hose but the axle lines are the same (I used the drum braked one) so no probs

I've done nothing else to the brakes and had no problems

One of the best mods to an older 90 much better than cleaning out drum brakes after every off road trip

Hope this helps

Steve
