Something that has been driving me slowly mental recently. A metric ton of fiddling and testing (and fixing) has shown it to be unrelated to the following:

-Alignment
-Wheel quality / buckles
-Wheel bearings
-Brake disc back plates
-Lack of gearbox oil
-Suspension condition (if it isn't new, it's rock solid)

The symptoms the car shows are as follows (Chris can attest to the weirdness)

-When the car is cold it behaves perfectly normally, no odd noises, no vibrations; works fine. Once the engine (and by proxy the gearbox) has heated up, accelerating or putting the transmission under any load will make the car pull to the left, with intensity roughly in line with how much accelerating force there is (more beans, more pull). When coasting or moving at a steady speed, everything is fine.

-When moving slowly and turning (for example accelerating out of a T junction / full lock), there is a rough vibration / juddering from the rear wheels, again this is fine when cold, only when it heats up. This is both forward and reverse, but more apparent when moving forwards.

-When the vehicle is jacked up on one wheel or both, attempting to turn the wheel you will hear a loud crunching, and the wheel will be difficult to turn. After comparing this with Chris's two (The legendary shedmobile!) this is worryingly more crunchy and stiff than what can be considered 'normal'.

Some videos have been linked below for reference, showing the kind of noise / play in the wheels.

If anyone has a clue as to what this may be it would be appreciated, though at this stage I'm honestly considering ripping it out and slapping a newer one in that I know works...... Alternatively, get rid of the engine too and slap a lovely shiny 1MZ in there... :icon_smile:
