Rumbling / grinding from front driver side
Two issues which seem related, and I’m hoping the wisdom on here can diagnose!

1. Consistently when hitting 18-20mph there’s a rumbling and what feels like movement from the front driver’s side wheel arch. Stops a few seconds later. It sounds like there’s something loose and rotating…
Local defender garage checked the wheel and bearings and said they couldn’t find an issue but there’s definitely something wrong…

2. Going over a speed bump it’s vibration and sound coming from the drivers front arch again… very similar sound but louder.. it also feels like it’s grinding and something is rubbing. It’s not a good feeling and feels like it might grind to a halt! Can’t find any marks on the arches from rubbing of the wheel and this happens with the wheels straight or turning.

Any ideas before I drop it back to the garage for another look?

Hmmm... From your description it does sound bearing related to me. Have you jacked the wheel up and checked movement top and bottom? There are 2 bearings an inner and an outer in the hub so if your garage just removed the drive flange to check they would have only seen the outer.

Do you have plenty of friction material on your brake pads? If they are very worn you can get a grinding noise where it is metal on metal.

I haven’t done it myself but the garage told me they did and it was totally fine. That’s really helpful - sounds like I should either take a look myself or have them look more thoroughly.

How easy is this to do at home? I only have the bottle jack from under the seat - nothing more sophisticated to work with. Very happy to give it a go but haven’t checked bearings before.

Thanks as always

Give it a go!
Level ground, Chock the rear wheels, handbrake on, and jack the suspect front wheel up with the jack on the axle. Only needs to be 2 inches off the ground

Check to see if there's any play in the wheel when trying to rock it top / bottom, you might even hear the rumble when you rotate it.

Have a look on YouTube there's plenty on there to guide.

Good luck, and let us know how you get on Thumbs Up

Remember - YouTube is your friend! Laughing

Just type in "check wheel bearings" and it will bring up a few videos showing you exactly how to check.

Sounds similar to what I had this summer. In my case I couldn't really feel any play in the bearing and when rotating the wheel there was only minimal noise that was hard to separate from a brake pad slightly touching the disc. But when I drove it it made the sound of a duck. Yes, a duck!
It turned out one of the rollers had seized or partially seized. That bearing was also rusty, but the other one looked fine.

To get into the hub and bearings you'll need:
13 mm bi-hex socket for brake caliper
17 mm socket for drive member bolts
Circlip plier helps
52 mm socket for hub nut
Depending on your seize and strength, a long enough breaker bar.
Torque wrench to get it all together again.
