Thread: Resonating Vibration In 110

Mr 88inch,
My drive shafts were chewed up noticeably.

I inherited a 2" lift when I bought my Deefa. It also has a vibration at some speeds and under load up hill before changing down.

At a recent 4x4 camping show in Brisbane I meet APTFAB. It was suggested to me that I needed new Radius Arms with a 3` change to make up the difference in the angle of the propshaft due to the lift.

I intend getting a set from them once SWMBO is not looking. There are a number of others on the market but I am going local.

Frankly I would put the standard springs back in it.

When I got my 110 it had 130 fronts & 130 helpers in the back, no disrespect, but it did not suit me or my intended use.

As well as raising the CG , it rode hard when unladen, and on the ramp the Axle Articulation was less than my standard 105 LandCruiser.

I put original 110 springs back in & then it was a little low in the front so I replaced the steel winch cable & rollers with Synthetic rope & Alloy hawse, and removed the heavy Steel steering guard & fitted the original one. Now 110 sits & rides perfect & Axle articulation craps all over the toyota.

I have put Airbags inside the rear springs for when I'm carrying a load or towing.

Now the 110 is perfect for all my purposes, & I don't have to spend a fortune changing all the other parts to make the suspension lift work properly. No good chasing dollars with dollars, I really think the Defender is better than anything else with standard suspension & tyre sizes.

I admit not having worked on many land rovers except an old series one so this would have surprised me. Normal practice is keep the ends aligned due to the action of a universal joint, in motion it speeds up and down as it changes angle/plane thank you for your insight into the minds of the Land Rover engineers it certainly is different.

Keeping the ends aligned is correct, but only if both diff and T/C shafts are parallel so that both joints have the same angle. On the coil sprung Landrovers they do not (the diff nose is tilted up to allow the track rod to pass under it), although on leaf sprung landrovers they do. This means that the two universal joints cannot compensate for each other's speed variations. The out of phase setup doesn't either, but apparently it is a bit closer.

OK, put in Disco 2 front springs, (very low and soft) and the vibration has all but disappeared on first glance. I will, however drive it like this for a week, as i am not convinced it is resolved.

Will post results.


(by the way, the cornering has been enhanced by dropping the front, less oversteer!)

Theres a handy landrover coil comparison chart here

looks like the disco 2 springs are lighter but aren't too far off 110 fronts
