Can someone tell me what size the bolts are that hold the bearing onto the axle? I need to replace a stripped one and my Dodge dealer can't seem to get the right part for me...3 different sizes they've shown me so far. Thnx

 

Are you needing length or diameter? The most common diameter is m10 with a thread pitch of 1.5 - length I’m not sure of.

Don’t you have the old one for reference?

 

I do have the old ones. I brought one into the dealer and they can't match them for whatever reason. I just checked it with one of my lug nuts....and the nut fit perfectly...which is an M12 X1.5 pitch I believe?? This is whacked

 

what year is the van and front for rear bearing? to clarify...you want one of the 4 bearing bolts.... not one of the 5 wheel studs for the wheel

 

2007 Grand Caravan, right rear bearing bolt

 

For what it's worth, the parts sites show the bolt as part number 06504450, which is .312-18 x 1.00" Long.

Seems odd to me, I would expect to see a metric bolt.

Take it to a hardware store and match it there, just make sure to get either grade 8 or 10.9 depending on if it’s sae or metric.

 

Yeah, that's what started all this...when they handed me the bolt based on the database...it was an inch too short...then they started trying different part numbers. They have ordered 4 of them for me, but it'll take ~5 business days to receive them, shipping from the US. I DID go to hardware stores and bolt suppliers and everyone had different ideas as to the size of it...some called it an M10, and some called it an M12...so right now I have a van on jacks in the garage at work that I can't even move...so hoping someone might have had a definite idea what size bolt this really is. Quite frustrating actually
