My X-Trail has developed a faint rumble that seems to be comming from the front offside wheel, it slows and speeds up with the car speed . I suspect a wheel bearing although it doesn't go off when turning the wheel left or right. If my diagnostics are correct how easy is it to change and do I need any particular special tools. I did change the nearside track rod end last week and still have to have the tracking re-aligned but I think this new noise is just a coincidence. Any help please

Hi pubcrawler, The X-Trail is noted for the wheel bearing locking nut working loose over time as I've experienced it myself about 3 years back now. I would re torque setting on nut first and check if it goes away. Nissan have known from the 1st build of the X-Trail that there is a problem that the bearing nut can become loose but they have never addressed it. I always check mine every 6 months or when I have wheels off as I don't fancy loosing a wheel.

To change the bearing you'll need a Hydraulic Press to remove it.

When driving over the weekend I have heard a high pitch whistling noise when I turn the steering wheel left or right. I havent had it checked out yet but could it be from power steering or perhaps wheel bearings? My XTrail is a 2006 2.2dci and has done 60K.

What is the correct torque setting for the bearing?

If a load of 49,030 N (5,000 kg, 11,025 lb) cannot be applied, carry out the following actions.
_ Assemble drive shaft and tighten wheel hub lock nuts to specified torque. Then rotate in forward and
reverse direction 10 times each to ensure a good fit.
_ At a rotation speed of 8 - 12 rpm, place a spring balance on hub bolt to measure torque.
SDIA0592E
Rotation torque : 1.645 N•m (0.168 kg-m, 15 in-lb) or less
Spring balance reading : 10.6 N (1.1 kg, 2.4 lb) or less
Rotation torque : 2.125 N•m (0.217 kg-m, 19 in-lb) or less
Spring balance reading : 37.2 N (3.8 kg, 8.4 lb) or less

The above is taken from Service manual CD, hope it helps.

A rumbling noise.... can have many couses. For instance a tire. Check the pressure and look for stones in the grooves. Saves a lot of work when the troubles (rumbling) come from that side. Wheel baring change is a lot of work... Also chack the brake disk: the blocks can touch te disk (Had the same with my Focus) Can be a damaged tire too.
Some tricks: Make a long drive. When the bearing is very hot, it can be the perpetrator.
Or jack the car up, turn the wheel round, a bit fast and listen through a screwdriver, blade on the bearing. Listen carefully. When you hear a strange noise it can be damaged.
Last trick is move the wheel (jack it up first) and controle her of side marging. Good luck!

Thanks Pubcrawler - but I wanted the torque setting for the bearing nut on the end of the stub axle to preload the bearing.

No probs, the details are in the pdf file in this post too

realist this is an old thread but I did not know about a potentially expensive bearing failure that could damage the wheel hub etc.

The Aussie Forum has suggested a castellated nut to stop the nut from backing off.
Has anyone sourced / used a castellated nut in the UK?
