Bad Vibrations

[Jeff J J]

Hi every one started to get bad vibrations on exaltation had this drama before but thought that I should get under the beast for a look. I was right the rear rubber coupling was shot. Mad how a peace of rubber costing less then £20 can make such a deference.

Yep, i think it's safe to say that thats had its day...LOL........... get shot of it and fit a regular prop instead!!

as ron said get shot of the rear prop and replace with a 200 one.

[Jeff J J]

I replaced the rubber with a new one today not a hard job but still a pain i only got that one fitted around a year ago. What sort of price am i looking at for the 200 prop and what is the deference. Jeff

[mobi]

the 200 has 2 ujs one at each end, they should be about £60. (may need the flang)
i find gkn dounts last longer then the cheap ones.

[Jeff J J]

Thanks Mobi one to think about for the future there. Jeff

One of the reasons the doughnut fails so quickly is that the prop is supported on a spigot bush that fits inside a rubber lining.  If that lining is worn it doesn't support the prop properly and the doughnut has to take the strain.  It will quickly thrash itself out even at fairly modest ride heights (MY LSE is lowered 1").

I  too suffered a similar fate , but it went unoticed until the drive home after the Birthday Bash.
Could only tow the caravan at 45 on the M1 because of the vibration and the machine gun noise
 underneath as the flanges batterred the bolts.

Hi Jeff

A quick look on e bay found some 200 tdi props for £20 to £30. You will need the rear diff flange from a 200 though. If you give Vince a ring (07970668091) He might be able to help you out. He has a farm on the Barry to Cardiff road and has Land Rover spare coming out of his ears !!

There are an ever increasing number of 200 series dicos in scrappies nowadays - there are 2 in my local one - one of them is going to be donating its prop and flange soon for the princely sum of a tenner - I've got new U/J's to put in it so job done.

I've got some really big cracks on my donut, so I'm keeping an eye on it for now, fingers crossed! :shock:

Ashcrofts do the spacer to fit the 200 flange on to the 300 About £7 delivered

spacer part no

Oh, so I need a spacer to fit the 200 diff flange to the 300 diff?   I thought it was just a straight fit - or is this a spacer to leave the 300 flange in place and fit a 200 prop?

[Disco_Stu]

Bingo. The doughnut acts as spacer amongst other things.

One quick point however. LR fitted doughnuts for a reason, I reckon the reason was because 200tdi's kept busting diffs. You'll find doughnutted drivelines break less often than UJ'd ones. True, the doughnut, even original (not pattern part) only lasts 12 months but they're still cheaper and easier to replace than diffs.

This by no means advice against changing, I run a UJ and 200 prop myself on my 300, just be aware of the possible downsides.

Cheers Wizard i will give your man Vince a shout see what his got out there could be a good Friend to have. The thinning with mates like that is you go there to look at a switch and come back with a winch  :) .

Good to talk again. Jeff

Interesting :-k.  I'd assumed it was an NVH issue, but then the 300 series also got the 24 spline axles, so maybe failures had become a problem.

[Jeff J J]

As with lot of Land Rover they started using part for next series my Disco is on an L plate and i have dramas some times with parts. Jeff

me too - it coincided with the fitting of the harmonic balance donut to the front diff did it not?  Its still sound advice though as its just plain physics as to why a rubber coupling would be better at absorbing shock loads than a normal stell U/J.......

[Range Rover Blues]

Not sure about Disco but on RC the harmonic damper appeared along with the EFi 3.5 engine and the thicker propshafts, slightly metricated suspension etc mid 1980's.
