I don't know. It might be clogged. I have no idea if there's a good and safe way of cleaning it all out.

Did you take out all the old power steering fluid and replace it?

No. It's normal weight power steering. Is it worse turning one way rather than another? Some of the front steering bits can go stiff with lack of use or wear. Mine was a bit heavy until I had something changed but can't remember what it was. Check front tyre pressures are ok as if they're low then a...

I'd be inclined to get it professionally cleaned and checked. You don't want it doing weird stuff with the gearbox.

Also battery and alternator. Any power issues and they're worth looking at to rule out.

If that power relay has any input via the F125 switch and that hasn't been replaced in a few years I'd probably start with that. There's a fusebox under the bonnet for gubbins as well. Couple of wiring diagrams in the Bentley manual that might help. Looks like there are a lot of earth points to check.

Are all 4 tyres the same with a similar amount of wear?

I'd think the long interval was the original planned one then a load of them failed so interval was shortened. There was a spate of snapped belts in a lot of cars when manufacturers started pushing out the intervals from the usual 36-40k out to 60 or 72k or beyond. Lots had to return to the normal 3...

V8 engine cambelt AND water pump is 4 years or 40,000 for a standard belt. You can get uprated belts that will do 5 years. All the tensioners need changing too. It's essential. The OEM water pump had plastic innards as well and the good kits have metal impellers. I did mine regardless. The mess if i...

No, the torque converter locks and unlocks all the time at all different speeds.

Vibration under acceleration is usually either inner CV joint or coil packs. Probably the former.

Oh. I thought it only locks at 40mph. Someone told me it did. Every day you learn something new

The torque converter does something at around 40 mph. It's called lock up. I don't have much more technical knowledge beyond that, sorry! I could feel 'something' on mine when it was around 38-42 mph or so. You could just feel there was something occurring. All I know is it's for efficiency as you r...

Isn't 40 mph where the torque converter lock up happens?

There is snow on the roof so I'd assume it's just cold weather...

At least you've found it!

Number 37 I think by the look of it.
