John,
I had a series 2, but was'nt sure (ie forgot) whether 2a's were different so I just generalised I knew Series 3 were railko type.

I'll second that, i had the same problem a while back, whenever it his ripples in the bitumen it did it, then after i got the track rod upgraded and the wheels aligned it made the problem worse so i rebuilt one swivel hub as the bearing had failed on top. Then i checked the panhard bushes, sure enough one was as loose as. Tweeked it tight and not a problem since. Matt

yes, that's OK, I thought you might have some info that I didn't. I thought the change was in early S2 production, but I have just checked, and the S2a parts book lists the change at axle number 24109240,25107785,24405088,25404199 depending on short or long wheelbase and RHD or LHD, which means the change was in early S2a production, I think in 1961.

Chev,
Do you mean it shakes from side to side, or is it through the steering?

Side to side could mean soft suspension bushes. I have just changed mine on the Disco and it is much better. If you can see any cracks in the rubber - change them. If they are over 80 000km old - change them. Do all of the bushes, it really is worth while and is fairly cheap to do if you do it yourself.
cheers Chazza

how loose are the swivel hubs after the adjustment.......?
you may need to have them a tad tighter.....we used to always do them a bit tighter than the book says......worked a treat......
but not too tight......you will damage them.....



but tightening of suspension is a must....it should almost be part of the service routine.........

About 4-4.5.

After all the good advice here, I am going to get under the front end and swing off everything this weekend. If nothing shows up, Ill revisit the hubs.

Thanks

Mate check back to some previous posts, I've done too many to mention, its the pre-loading on the king pins, I can't think of the lb (may be around 8lb +/-) as you get the feel of it after so many, there is a need for some pre-load on the king pins to stop what your going through.
Sorry can't be of more help,
Cheers

Panhard bushes and swivel pin bearing preload.
