Whine at 30-40 mph?
 
I have a whine at 30-40 mph- no wife present!
I’ve searched & noted this could be a number of things:

Worn tyres
Low gearbox oil (getting a full check/ change tomorrow)
Worn wheel bearings old. OE ones letting in rain/dirt?

Now how do I know which wheel bearing it is apart from the usual jack it up and wobble the wheel?

Any tips welcome!
Cheers- loving the car so far, just need to sort a few niggles that’s all!

Unlikely to be wheel bearings. When they fail they just make noise at all speeds.

If your gearbox oil is low it wont work at all!

Could be a bearing in the tranmission train somewhere.

Most likely to be tyres. Some brands will produce noise at various speeds.

I’ll be honest, the tyres are all Mis-matched old crappy ones by the look of them, I got the car as a cheap p/x so I knew it’d need a few quid spending on it.

If the tyres are like that then you might find a new set transforms the car.

As has been said, if it were a wheel bearing the noise would get worse with speed. Does the noise change if you swerve the car left or right?

These cars are like a new girlfriend, you need to have been with them a few months before you understand all the noises they make and how they are showing their age....

In that case I’ve picked up a right old dog!! 😆😆

No but when I coast the car is smooth & silent! (That would eliminate wheel bearing too?)

Hopefully picking up 4x part worn Goodyear wrangler hp tyres tomorrow-
I’ll get those fitted & 4 whee alignment too.

Good choice. I've found the Wranglers to be excellent and quiet too.
