Any one know the size bolt for a hub bearing on an 02 sport 4x4? Im pretty sure i got a bad hub when i replaced it last week and the inverted torx bolt on top was a kinda rounded over when i got to it. Wana replace it so i have a good bite when i torque it down after the second replacement tomorrow

For anyone replacing the bolts - this is the original bolt:
- https://www.idparts.com/knuckle-bearing-bolt-liberty-crd-06503088-p-10027.html
- https://www.summitracing.com/parts/mop-06503088

- https://www.moparpartsgiant.com/parts/mopar-bolt-knuckle-to-bearing-attachin~6503088.html

The original is somewhat difficult to find - at least at the time of my search, multiple sites had it as not available.

Mopar part number: 06503088
Dimensions: M12 x 1.75 x 43.00

I found this quite good looking replacement: https://www.ebay.ca/itm/235400094399 , had it ordered, it claims to be 12.9 grade steel.
As one of my bolts has stripped head, I'll attempt to use https://www.amazon.ca/dp/B0D2BKXCD7 temporarily, if there's enough space for the head/socket, and I'll report back.

So, the bolt from Amazon (https://www.amazon.ca/dp/B0D2BKXCD7) worked without any issues.

There’s plenty of space for the socket, at least when installing with steering knuckle out, and I don’t see any issue with extra 2mm of length.

(I replaced only one bolt that had stripped head for now.)

Still waiting for the bolts from eBay.

Working on an '05 Liberty Sport...

Not sure why I thought any of the existing E18 bolts would be reusable ... nothing else has come apart like it should ... both lower control arm mounting bolts were seized, so had to break out the sawzaw ... the upper balljoint nut was seized, so I had to use the nut splitter ... and although the bolt holding the clevis to the lower control arm cam out, it tore off the metal retaining tab ... and then to top it all, CV Shaft wont separate from the hub even with 7 tons of force applied ... At this point the only thing in the front drivers thats going to be original, is the clevis fork, the caliber and the wheel rim!

So I ordered the same bolts from Amazon (same part number) but although advertised as 12.9, when they arrived, the box says "Carbon Steel" and they are stamped 8.8 ... M12-1.75 8.8 bolts are only good for around 60 ft-lb, and those are supposed to be torqued to around 100 ft-lb, you could say, I'm not happy, as it wasted three days waiting for their arrival and a couple more days for the replacements. But I am glad I checked the torque requirements.
