|
|
|
300Tdi Defender, 2" lift, standard radius arms.
Runs fine at low speed, but when coming down from 50mph+ there is a mild shudder - which wasn't there before the lift. There's also a mild vibration at speed, but that could simply be the fact that it's a Landrover.
Wouldn't be too worried, but we're heading off to Morrocco in October and don't want to have to change UJ's on the side of the road or do long term damage to the Transfer box / diff.
I had decided on Double Cordon, but the supplier today thought I'd get away with a wide angle? Also some suppliers sell the wide angles at £130 while others are £170. Is there a difference?
Any thoughts?
Many thanks for any help.
Craig

Craig,
This depends upon what is causing the vibration. If the vibration is due to the yokes of the UJ 'clashing' due to increased angle then wide angle prop would do; if however the vibration is due to the fact that the ends of the props are no longer parallel then a double cardon prop is needed.
You can tell by looking at the prop (at the transfer box end) and seeing there are any tell tell marks on the prop yokes.

Nice one thank you. I'll have a look tomorrow am. I suspect that they arn't clashing - that's my guess.
Checked for wear before I took it away (1200 miles ago) and there wasn't any play.

Sounds like something wrong with a propshaft to me. The rest of the world seems to get on fine with 2" lifts. Check 1st that your propshaft yokes are exactly in line and not at say 90deg to each other. Roll it one way or the other untill one yoke is horizontal and then look at the other end of the shaft and see if it's the same. The prop might have been split at some time and put on wrong. Chock the wheels and check the play in the shafts with the handbrake off and no difflock applied. Any play in the rear prop will be invisible with the handbrake on.
Silly things like mud on the inside of a wheel can cause what you say too.
If for some reason the flanges are way out of line then so's your castor angle on the front so you might want to look at that.
