Bad Vibrations

<< < (6/7) > >>

Range Rover Blues:
No it should run fine at quite a noticeable angle, mine does, my car is lowered 1 inch but in high profile it's about 2 inches above standard and I get no problems.  In fact I think they dope ok with 2 inch lifts on coil sprung cars, where they run that height all the time.

If you still think it's the back prop then you best bet is a 200 series prop and change the input flange.

Hi,
Hmm, well if thats the case I dont know where to go next. Looks like we might have to pull the rear diff and see what's up.   :?  It i soooo specific in the speed area and under load too. Very light load it is hardly 'feelable' and it is worse when the driveline is cold. Is that another clue?? :roll:

Range Rover Blues:
Well oil is thicker and rubber harder when cold :-k

Here's a thought, if it really is better when it's wrm, measure how warm each part is, say the diff, gearbox etc.  if it's a few degrees then I'd be sceptical but if say thegearbox is getting quite a bit warmer then perhaps it makes a difference.

I can see you chasing you tail on this one though, as you fix one part then another that you thought was ok is now the bit letting you down.l

I gave up trying to sort my steering kickback out and fitted stronger shocks for that very reason.

nzoliver:
[!Expletive Deleted!]! :doh:
Should have read wot I typed. It is better when cold not worse. Worse when hot.  :roll:

I wonder if it isnt the top locator arm bush or shocks - either a binding one or they are too sloppy but the truck doesnt seem to bounce at all. In fact the opposite - this is a very harsh truck. The 2 lower sway arm bushes have been swapped for Nolathatne. Dunno why. The rest look ok and are origonal.  :-k
Chasing me tail is chasing me out of this truck and into the SII v8 i've got coming that I was going to sell.

Range Rover Blues:
Ah, hard ride, bit of a clue.  Try slackening the shocker bushes half a turn, amongst other things you might be trying.  With a beam axle you have to let a small amount of vibration go unchecked.
