MX5Ireland

Have been using the 5 for last few weeks as main car got pranged (by my brother-in-law, while I was on hols). Anyway, this morning on way to work got woefull shudder, which felt like a puncture. Stopped, checked around & all ok with wheels/tyres. Resumed journey, only to have it start again after about 15 mins - seems to kick in only with accelaration and/or over 90kph.
Any suggestions (Leading to concern at sunday participation... )

Shocks??

Might be worth getting your wheels balanced if ya cant see anything obivious

heh the "65mph shimmy" I have it again too.. got rid of it years ago, but its back... can be caused by a combination of things.. usually stuff like :
Tyre pressures, Tyre balancing, Bracing helps (under gearbox, between seatbelt towers, between rear suspension), etc

Hi,

I had the 60mph shimmy, caused by deformed tyres (it had been left standing for months B4 I bought it). However if you get it with acceleration below that speed, I'm thinking that it's perhaps not related to the tyres/wheels.

Funny story - I found out about the shimmy when I was in the UK, and when I took the car into kwik-fit in Preston, the guy asked me, in his broad Lancashire accent "duthey not 'ave kwik-fit in Ireland, then?"

Not the sharpest tools in the shed, some of these guys!

Yeah suffering with that myself at the moment. it's feckin frustrating.

Must get the wheels balanced and see if that helps

Problem is drive-shaft. Was diagnosed in the pub by two independent experts!

Ahhhhhh, it must be true so

This one again....have not had the shaft sorted, but hoped the problem would disappear miraculously in the garage over the winter
So anyway, went for quick spin yesterday, and lo-and-behold but didn't the whole world start a shakin' & a-shudderin again after about 10-15 mins - accompanied by intermittent burning smell .
So headed back to base for inspection.... front right wheel almost white-hot!!! Methinks I have brake problems - minor eurica-moment (I'd had new discs fitted before this started happening but never made the connection).

Have now spoken about this with mechanic friend (who is also an MX owner)... sticky caliper or warped disk is the phone-diagnosis. Healthy/happy car is within sight....... bring on the outings!

Easy to miss.... Check the wheels are centered and Tight.
