ongoing vibrations in my 110

[jx2mad]

Well, I have got rid of a lot of vibrations by replacing the front drive shaft and fitting a new universal to the rear shaft. However I still get vibrations between 75-90 k/h. Any suggestions? Jim

Sometimes, if your leading arm bushes under the axle are shot, it allows the axle to rotate enough to make the front and rear drivshaft angles to be unequal.

Is your truck lifted?.It is common for them to vibrate at certain speeds.At least mine did. Pat

All bushes seem ok. The 110 is slightly lifted in that it has aftermarket coil springs which are taller than normal. They are also softer.

Have you had your d/shafts checked for rotational balance, both of mine were out and it made a significent difference. Check the condition of the splined sections, the amount of wear/play, will also affect the balance.

my freelander had vibrations .....turns out the michies on the back didnt like the yokes on the front....put a new pair of pirelli and solved the prob

Thanks to all. I realise my tyres are fairly well down and maybe worn a bit uneven. Hope a new set will fix problem.

Also look at your steering damper. Most 110s have a vibration at some stage and is often attributable to a fatigued damper. I have just done my suspension and damper 4WD1 RTC and this eliminated nearly all the vibration and unwanted feedback to the steering wheel.

The front drive shafts on Defenders are supposed to be out of phase by (I think) 21 degrees. If the new drive shaft was balanced and installed with the uni yokes in phase, then this may account for the vibration. The 'out of phase' angle is there to compensate for the upward facing end of the front diff.

In phase the yokes on the drive shaft match, a D and a C shape on each end. Out of phase is when the D and C are a few spines out from a perfect match.

That was the case with countys and RRs, so I presume the Defender's the same, I'd crawl out and double check mine, but it's raining.
