Vibrating e34

[Quaser]

Hi Guys

Just got a cheap e34 for my mate - it was cheap cause it has a little bit of bodywork damage, and the steering violently vibrates @ 60mph

I later discovered that the violent shake is between 60 and 70 only, and i ave taken it up to 100mph with no problems (i really miss my old one now - such a cruiser!!!)

anyway - any ideas what it could be? i can rev it all the way to 6k no probs when accelerating - only at that certain speed does it vibrate!

apparently wheels have been balanced!

weird one!

I've got exactly the same kind of shake but at 60mph.

I think it might be front top mounts.

I'll get a few people to look at it and let you know what they find.

but it goes after 70 - how bout yours?

E34 are renowned for this , could be a number of things and, sorry there is no easy way, tie bar, track rods, mounts even your wheels need balancing or a combination. Iv had one and it took for every to sort it. I enven replaced the steeringbox as it was to tight.

track rod end, top mounts, crap tyres (they can look like they're balanced, but they're not - trust me!) or worn bushes can all produce this symptom.

My shake was 50-55mph - swapped my apparently-balanced wheels front to back and it's stopped most of it now...

Hope this helps...
