I have had a steering wobble when braking at oth 110kph and 60kph.
Had brake rotors replaced
Steering rack replaced all aparently as a LR fix kit.
Did not fix.
Later machining discs stopped it for 5km but now returning again.
D4 has done 70k km and about to run out of warranty.
Not thrilled but the rest is great.
Back to the dealer yet again. They have been very cooperative so far.

I had also some steering wobble under braking but it was solved after tuning up the axles setting.

Before doing the tune up, the dealer tried to solve it replacing the brake discs but without success...

My D4 has already done 92.000 kms and the discs are still the original ones...

Cheers!

Exactly what did they do in the 'axle tuning'?

According to the dealer, the axles geometry parameters were just out of range.
How many degrees out of range? don't know...
Reason? also don't know (I bought the car with 60.000 kms done)

All I can say is that after tuning up the axles (into LR parameters) , the problems of vibrations and steering wobble were almost solved.

However I still feeling the steering a bit lighter and soft (specially under acceleration) so I will ask to the dealer to refine even more the axles, especially the camber degrees.

Cheers

I think we are talking about a four wheel alignment?

Yes, "alignment properly done" ...better said, in my modest opinion.

The shops around my town usually check just the convergence parameter when the alignment is done.
Camber parameter is not commonly revised, since not all the cars have this possibility.

In case of my D4, the problem of camber adjustment was noticed only by the dealer.
(previous alignment was done by the tyre shop where the tyres were replaced).
