Noise from the rear wheel?

[kentc5]

Hello guys,

This is for my Xantia... if I take a turn usually right turn with 70mph on the motorway ... I will hear a kind of humming noise from the rear driver side wheel.
If I take the corner with less speed it will not make the noise, if I take with more I cannot remember ...
the sound, sounds like the car has 4 wheel steering and the rubber rubs on the body .... but I am sure it cannot be the case as there are no marks on the tyre lol ...
Also when this happens the car does not vibrate or anything else... it is only a noise.

Cheers

Rear hub bearing?
Cassy had it happen to her O/S one.

Funnily enough the Xantia does have 4-wheel steering (of sorts), although It wouldn't be causing this issue. I would also say the wheel bearing is a likely culprit.

Is that a big job to do for my self... does anyone know to point to a hot to guide of some sort?

Reasonably simple, the only sticking point would be getting the brake caliper off. I've seen a few posts here that say they can be a real 'mare to unbolt, having not attempted to remove them from mine I can't really advise. (anyone?)

Apart from that, the only special tool you'll need is a decent puller to get the hub off the stub axle.

For whatever reason the bearings themselves aren't renewable, but the hub and bearing assembly is available for basically the same price as a new bearing (about £40 on ebay).

You're spot-on with the depth of the job Chlorate

The caliper can be a right 'mare but with care, attention and some patience and delicacy it's often OK more than it's not. Also, being an Estate the bolts are bigger and a little less prone to shearing...

There's some good threads on caliper removal Kent and one long one in particular will tell you all you need to know and a bit more besides...

Hello Kent,

In my first Xantia I had a squealing noise whenever I had a heavy load, and I found it was the rear bearings. Replacing them solved that problem.

When you first posted with your Xantia estate, I made several replies. The last one I did was re the caliper corrosion issues known to affect the Xantias and C5s, with a link to the best way to resolve it (with pictures of the steps taken on a Xantia by CitroJim). If you have to replace the rear hubs, you will have to take off the calipers, so I would take the time to sort out the corrosion (if it exists).

There is something I intend to do soon, and that is to make a couple of gaskets (out of a plastic bottle, unless experts say otherwise) to fit between the calipers and the trailing arms to try and prevent a re-occcurance of the problem.

I think a plastic bottle may be too thick. Some thin polythene or greased paper might be better.
