Thread: Failed front wheel bearings - where did I go wrong?

Britpart bearings ??

Negative.

I would not rattle gun the bearing on & IMO no need to go past 450 , The Iveco 4x4 uses similar unit bearings to the D2 , 650NM rear and 450NM up front, I have a 3/4 drive 450nm torque wrench & do the front & rears up to 450 . Ive had an original rear SKF fail at 70k (probably tightened past 650 because it took a 2m extension to crack it off) , bought a Febest bearing (similar price & reputation to Britpart) & tightened to 450 & no issues so far, 30,000km on. 650 is too much in my book.

Yeah it’s loads isn’t it.

How long is that torque wrench of yours and does 450NM take max effort?

First one that failed I thought perhaps I’d not given it enough, so second one I gave more..... and it failed after half the miles.

Annoying.

Why do they need to be so tight?
My series wheel bearings are only finger tight and have a little backlash in them. Last for ever nearly.

stupid pretensioned unit wheel bearings , I HATE them with a passion , give me dual tapered rollers any day.

heres a knackered one from my Iveco, $600 in Iveco box, $160 in SKF Box $80 in Febest box

My 450Nm torque wrench is a Meter long, i'm 100kg & have to sit on it & bounce

So 100 kg x 1 metre equals how many nm?
