Hi
I hope someone has had experience with this as I am having trouble finding info on the web.
My service manual on my 2011 2WD BT50 says front wheel bearings should be regreased every 20 000km. I have a workshop type manual but it gives no further details whatsoever. From going back through service records it appears that this is never done. My ute now has 60000km on the odo but it appears the wheel bearings have never been regreased when being serviced. This is at three different service points. Is it a case of leaving them alone and replacing when they start to make noise? or have all the service people (including RACQ) overlooked this?

Comments welcome.

My workshop manual (Ford/Mazda DVD) indicates the bearings are sealed and a press-fit into the steering knuckle and therefore not serviceable.

Did you talk to the people who serviced it first and get an explanation as to why it wouldn't be done. Wheel bearing are not usually an item that gets regreased regularly they would usually be good for hundreds of thousands of km both front and rear and it would be labour intensive and a costly exercise for this type of service to be done at regular intervals also if they pulled it apart and there was rubber seals or gaskets in there they should be replaced which cost money so just keep driving and don't worry about them. Usually a mechanic would jack the vehicle up and check for play in the bearings and tighten them if required and that's about it.

Batts the information your giving is WRONG big time....Front wheel bearings need to be serviced unless they are sealed units then you you have no choice but to replace .... Wheel bearings wont do hundreds of thousands of ks unless repacked with new grease, and re adjusted every 50,000ks or even less, Toyota recommend ten thousand.

Cheers Axle.

My GU Patrol had to have front bearings regreased/packed every 40,000km. Agree poor advice above about forgetting about them. Nothing worse than breaking down in the middle of know where!

Guys,

It all depends on the vehicle. Not all 4WDs have agricultural front wheel bearings that require regular re-packing.

My 120 Series Prado had sealed, maintenance-free front wheel bearings. There is no provision for adjustment or re-lubrication.

Ditto my 2011-present Mazda BT50.

The OP's question was about a 2011 BT50, not a GU Patrol. The workshop manual for that model indicates a sealed bearing that can only be removed and replaced by removal of the steering knuckle and use of a hydraulic press. Hardly something to be done every 40k.

The OP is talking about a 2wd. I have never had to work on one of these or the 4wd variant.
Is it possible the 2wd have sealed front bearings and the 4wd have serviceable bearings?
I have seen quite a few maintenance manuals that don't have the attention to detail they should have.

No, Pop. The factory manual indicates both have sealed bearings. A slightly different procedure for removal and replacement of the steering knuckle, but once that is out work on the bearings is identical.

If you read my comment I said did he ask the people who serviced it as to "why" they wouldn't have done it then he may have got the answer he was after. Also maybe I also should have wrote 'Your" wheel bearings are not usually greased regularly I was cementing on his vehicle and not every different make on the road.

AXLE ---- I think that the information that you are giving is WRONG big time, given the experience I have had with a vehicle that I owned whist I was in N.Z. I purchased it with 106800km, sold it with a further 150000km travelled --- a total of 256000km. I don't know if the front bearings were replaced prior to my purchase , but I can safely say that they had done 150000km with out failure and any repacking.

What you have posted does not agree with my experience.

My thoughts are on re packing as specified by Dealers is that they can charge for something that they don`t always do.

The vehicle did get a rebore during this time though---------

Regards G.T.

That's a lot of ks without knowing whats been done GT!.

A wheel bearing can collapse in a instant, think about it when on a freeway, and more importantly the others around you!

To keep driving to they fail or start getting noisy is a bit risky in my opinion, but every one to their own I suppose, I just think theres enough accidents out there without encouraging anymore.

If a Dealer is pacifically asked to check wheelbearings, and doesn't,

Then God help them if something goes wrong.,because of that neglect.

Just my Take on things.

Cheers Axle.

I used my GU as an example. The OP needs to find out what kind of bearings he has. Just forgetting about them is not good advice.

Axle ----- A wheel bearing will collapse, but not in an instant. Prior warning will be apparent even to a person with out any mechanical knowledge. Noise , which comes more and more apparent as it deteriorates, especially when turning corners and a feeling of instability when steering eg wander etc.

It is not such a safety issue as you may make out. Vehicle inspections are carried out, say in N.S.W.-- once a year -- Pink slip.
All is done is that the front wheels are rotated and checked for noise, and for play. IF o.k. that is it for another year.
A vehicle could do 1000km or 100000km in that time. If it is such a safety issue , you would think that inspections would be at more frequent intervals. A wheel bearing will eventually collapse, not without giving adequate warning, which has to be ignored for quite some Km`s Regards G.T.

Yes generally you do get some warning when a bearing is going but it will depend on how bad it is if you can keep driving. I had a 4 runner front L/H bearing suddenly started to grind at 170,000 km just turning onto a freeway had to get towed. My current GQ rear left started grinding at 420,000 km but I was able to do around 400 km then get it fixed.

Kcandco

Batt is probably half right
Wheel bearings from new should last at least 100,000 km on a new vehicle as long as they are inspected every 20,000 km or so , and that is a simple process and not expensive.

I'm with Mark on this one, having serviced or replaced the odd wheel bearing or 2 in my life.

As long as the seals are in good condition and no water or dirt has entered, and the end play/pre-load is checked at time of service, they should go at least 100,000 k's.

As an example my old 1991 Cruiser has still got the original bearings that Mr Toyota fitted in the factory. Only a baby with 300,000 on the clock, and being a mechanic, she/it gets all the love and care lavished on her.....NOT.

Sealed wheel bearings, sealed uni joints, what a wonderful idea....also NOT.

I have spent a few years in the motor trade in my younger days and my car gets much the same treatment. In forty years of marriage my wife has never ceased to be amazed at how little I do to our cars yet they never stop. The trick is knowing exactly what to do and when and that can vary considerably in accordance with the conditions it is driven in, particularly with 4wds.

It is no use sticking strictly to servicing schedules.

Gents,

A recent experience with wheel bearings.

Just had the front and rear suspension reconditioned on my Falcon sedan. Amongst other expensive items, they replaced both front wheel bearings, as one was a bit "rumbley". They'd done 190K kms.

The bearings are fitted to the hub, so one buys a new hub too.

On Toyota bearings, my 79 series has done about 290K clicks, on the original bearings, usually try to repack them every 40K, but that doesn't always happen! :-)

Like Pop, not too sure about these sealed wheel bearings? Might be okay on a Falcon/Commodore/Mazda 2wd, but good to know what's going on "down there" when one is prepping for a trip. Checking the cups and cones might just avert some grief further down the track.

Bob

I agree with Frank P. Not all vehicles are the same for example my 2000 model Troopy's Warranty and Service booklet maintenance schedule says replace grease every (believe it or not) 20k Km, I know mine had not been done so at 160k I inspected both front and rear, they were all in perfect condition the grease still looked good,no hardening at all but I replaced it anyway because of all the work involved to strip down for inspection it seemed a shame to do all that work or nothing. I'll have another look at say 300k Same as my sons 1995 80 series, stripped down at 330k as we didnt know when or if they had been repacked previously and they were fine, good as.
I expect the manufacturers give those intervals as a arse covering exercise.

cheers......jeff

kcandco,

To end the doubt and resolve the conflicting opinions to this point I checked with my dealer.

Is your BT50 the current shape which I believe was released in October 2011? If so the front wheel bearings are sealed and only require INSPECTION every 20k .

If your 2011 BT50 is the previous shape (prior to Oct 2011 and smaller than the current model) your bearings require re-packing at Mazda's recommended intervals.

Thanks everyone for trying to help out. The vehicle had these services done by previous owner so not sure of reasoning. Maybe the dealer didn't know or want to do the regrease. I will now look into procedure for doing the job. As all my previous vehicles had long life bearings. I wish this one did too.
