Steering wobble, increases with speed, violent at 50mph+

[coolspot007007]

I noticed a bit of a wobble throught the steering recently but haven't been above 40 for a while so didn't think much of it. I thought the lower gearbox mount was the culprit (have already changed the upper mount, dogbone and upper gearbox mount about 3 months ago). Anyway went on the motorway yesterday and it's ridiculous above 50mph, it feels like a side to side wobble through the wheel but it eases off when you stop accelerating. In the past 6 months the car has had 2 new wishbones, a new track rod end and wheel bearing (nearside), new top mount kit, new inner and outer ARB bushes. A few weeks ago it had new front discs and pads but this wobble has only been apparent recently. The front wheels have been on and off a few times since then and I've swapped the fronts to the back today and checked the tyre pressures are all correct (32fr/30r) with no change. I was going to have a look at the dogbone tomorrow, but could it be the shocks possibly? I remember going over some cobbles a few weeks ago and it seemed to be rattling about quite a lot and the ride in general seems worse than it used to be
over potholes, but generally ok (am running prolines and standard shocks). Any ideas?

had a similar problem which turned out to be a driveshaft

Was hoping not to hear that, no clunking/knocking around corners though and sailed through the MOT last week.

Wheel balancing issue can cause this.

Have changed the fronts to the back though, not even a slight change.

drive shafts, one of the vans at work had damaged drive shafts and it wobled the steering and car until going over 60mph. ( dont try that!!)

get it checked out for faulty drive shafts if im tbh

I also had a similar issue which after many weeks of head scratching turned out to be a fubar'ed diff in the gearbox.

How violent is violent?

Hard to keep in a straight line, didn't feel safe for more than about 5 seconds at 65, entire car rattling by that point.

Well I popped the offside shaft off and opened up the inner CV joint. All the grease was grey/silver with swarf everywhere, here are the findings:




Gouges and scoring



And the actual cause.
