A few months ago I changed both front wheel bearings.

A couple weeks ago I noticed, every now and again, when I turn to the right
I get a squealing sound coming from the front left.
It does not happen very often.

I am thinking that this may be the front left wheel bearing?
Perhaps it needs to be tightened?

If it is the bearing that is making the noise does this mean that the bearing is already damaged and needs to be replaced?

AND, are the front bearings the same as the rear?

Thanks.

Squealing when turning could be a powers testing belt.

Did you set the preload on them right?

You could always just whip the outer one out and check the condition. Pretty quick job if you've got a spare gasket.

Powers testing? Power steering, perhaps?

Doesn't do any harm to pop the drive flange off and have a look, and make sure there is plenty of grease in there too. Try to wobble the wheels and see if there is any slack too.

Just jack it up if no play bearings probably okay, what make bearings did you fit?

Might be a stone caught in the splash guard or something?

Are the front the same as the back?

When I originally ordered I purchased 4 but only installed the front.

Thanks.

Pretty certain same all 4 corners

All the same, is yours a td5, if so the bearings are a slightly different set up.

lynall · Jul 6, 2015

But can be fitted with the earlier type.

If not they won't be able to be tightened up.

i take it you preloaded the bearings?

Preloaded?

300tdi.

Not sure on a 300tdi but on the 200tdi you can set the preload with a dial gauge as per manual or tighten the adjuster nut to 60nm to seat the bearings, then slacken 90 degrees and tighten to just beyond hand tight. Check for play by rocking the wheel at 6 and 12.

Yes, that's pretty much what I used to do with the old adjustable ones. Get it tight to settle the bearings in, then back off a fraction so you can turn the wheel but don't have any slack. A tiny bit of resistance is OK, but you don't want too much! With some tapered bearings the manufacturers recommend a torque preload on the adjuster nut (I seem to remember doing a Peugeot's rear wheels like this a while ago) but I don't think it's recommended on Land Rovers.

Later models have a spacer between the bearing races and a single adjuster nut.

Also use earlier nuts ie two nuts and lock tab.
Dont forget the thrust washer otherwise they wont stay adjusted for very long!

Is it not preload to 60nM then loosen and torque back up to 6nM?
