Front Wheel Hub And Bearing

[bignev]

Sorry Fellas put a wrong heading on the other post and can't figure how to delete it!!

 

Has anyone replaced and sourced a correctly made front hub / bearing?

 

I ask that way because I've had 2 different ones, including from Jeep Chrysler Parts, without the shouldered wheel stud.

 

So the discs can move slightly on the stud, no matter how tight they are. There is a lot of force when you accelerate and brake! And it will probably do it every time.

 

Mine is petrol so I heard it the first time (I hold my hands up my garage mate did the swap in a hurry for me) when parking it up at home, forward / reverse etc.

 

Of course, over a long enough time, this could lead to failure, and then accidents, and why it happened legal cases, just because the after market industry doesn't realise the importance of that shoulder, rather shocking.

 

It may be that the noise of the diesel engine will easily hide the clunk as it does it.

 

Anyway some pictures on ebay clearly show them without the shoulder!!!! But JeepChryslerParts had a shoulder - but not when they arrived!!!

 

The part number is 04641517AD and are available from Chrysler UK, but at £230 each was trying to avoid that. With import duty it's actually more from the States, bugger.

 

This could be interesting.

Got 2 for about £76 of Fleebay, one been fitted and tother getting fitted tomorrow. Will take some pictures of second one if that helps.

Right enough there's no unthreaded bit of stud on the studs but won't know till tomorrow when I can see old hub. Could always fit a bit real short copper tube to make the shoulder. but its going on tomorrow anyway.

Look like their made in Poland. 

[bignev]

Yep they are same as the ones I had, not as per originals.

 

Just see how much that stud moves in the disc hole!!

 

Managed to land on one original, with shoulders obvioulsy. Got another on the way from a local "USA" parts "specialist", will let you know next week if it's correct, after I went in and showed them the OEM part, lets hope so hey.

Got some picts but won't add from this Tablet. Old hub studs have shoulders yes but if you wanted you could maybe swap over the studs as they are just splinned in. But on thinking about the movement between disc and hub, 99.9% of the time you are braking while driving forward so disc will be up against the studs on the same side most of its life.

Oh and another thing, keep a spare pair of control and steering arm ball joint rubbers in your stock just incase as my steering one is shoot. Shoot yet again that is as replacements are very short lived, like less than a year.

Right enough old hub studs have a shoulder..Well thats both my front hubs renewed and I have never known this car to be so quite since ownership nearly 5 years ago..

Abs light was also coming on most days and that's it sorted after finding it was rubbing on the CV joint in the last hub replaced today.

Ah yes, good point that is Gordy. My brain hadn't calculated that one properly. More concerned than I needed to be.

 

And if my old hubs hadn't been binned that would be a relief of an option, but sadly too keen to get rid of scrap - tits. Never too old to learn hey, I know better than to bin stuff before the new has been proven, good reminder!

[gordy]

But on thinking of not having the shouldered studs, whenever you remove the wheel the disc is going to be extremely slack and  coggle outwards. The problem of this is a bit rust or dirt may get down between disc and hub and hence put disc as well as wheel out of true. Think I might try a bit thin copper tube in there next time wheel is off. Or wait just remembering those spring clips/locking washers that used to be used to hold disc against hub for this particular job at one time.

I'm thinking there is way to much thought going into this. These hubs wouldn't be on the market if they were found to be a danger.

[bignev]

You could be right, but you haven't heard that noise it makes!

Once they are on, and bolted up I wouldn't think much will get into it to distort it, but rust is a strong if slow mover.

[Semmysonic]

I'd be more inclined to think the noise was from the brake caliper as aposed to the disc.

The clamping force between the wheel and the hub should me more than enough to stop the disc rotating. If not there would be a lot of sheer force on the studs (even with the shoulder)

[bignev]

That's the point, there isn't enough force to stop the force of the engine pushing / pulling a two ton car and rotating the studs in "oversize" holes.

 

There is a shed load of sheer force on all  car wheels, but normally no "shock" effect. The sheer load required to cut through 5 studs simultaneously is absolutely huge.

 

To test it, foot on the brakes holding the pads and disc tight, a small amount of throttle and CRACK.

 

Don't forget this isn't my first GV, it's my third, and we've been doing that parking manoeuvre for 5 years, reversing on to the drive, usually with the window down. But I heard it with the window up.

 

And this car didn't do it before the hubs were changed.
