Kangeroo juice!

Hello!

Browsed this site a lot whilst looking for a M35 to buy and after for mods etc, it's been very helpful. But I've signed up to ask a question of my own as I can't seem to find an answer. 

 

I've owned my 250 RX Four about 2 months now and I love the car. Except the past week it's developed a really weird wobble. The car shakes backwards and forwards between roughly 20kph and 70kph. It feels like I've fueled the car with kangeroo juice, which I promise I haven't here in NZ! 

 

It does the wobble regardless if I'm on or off throttle, doesn't come through the steering wheel and the car pulls straight. I'd like to say it feels like it comes from the rear but I couldn't be 100%. 

 

So far I've checked the basics, wheel nuts are tightened up, had a quick look underneath and nothing looks out of place. Done a quick finger gap test of the arch gap on the rear and it's the same both sides. Revved up the engine and it didn't seem to flex too much so engine mounts seem fine. 

 

My next thought is wheel balancing, I do need to change the rear tyres soon so fingers crossed that solves it.  

But until then what's people's thoughts on what I could be or what I could check? 

It's annoying as I have next to no tools and only the boot Jack to lift the car as I'm only here as a back packer from the UK. 

Cheers guys!

 

 

Oh here's a picture of it too, just cause no one likes to look at topics with lots of text and no images.

You haven't accidentally turned on the atessa lock (the one that lights up the two axle light assuming that the M35 is the same as the C34 in that regard)? Loose universals on the driveshaft? Recently fitted unequal front and rear tyres?

maybe wheel bearings..

jack up each corner , and check wheels for play.

grab the tyres , push and pull hard in all directions

otherwise gearbox or tcu could be playing up.

have you or the previous owner had the transmission serviced ?
