R53 Carrier bearing bracket bolt size/thread pitch?
Hey all, my r53 decided to toss all three carrier bearing bolts into the void, allowing the passenger side axle to pop out just enough to immobilize it. Can't seem to find any replacement bolts anywhere so I need to figure out the right size before I head to the hardware store and buy a dozen different bolts in hopes of finding the right one. Does anyone here happen to know or have a set laying around?

Just remember to loctite them. (Blue strength is recommended)

Yeah man it happened at the worst possible time. Just changed all of my fluids and was headed out for a camping trip. Filled up and went home to grab the wife and the axle decided to pop out right across the street. If my luck was just a little worse id be stranded hundreds of miles from home.

@nameuser Glad it wasn't worse!
Luckily my axle never popped out but I noticed the 3 bolts securing the carrier had backed out by a few threads.
Having never touched or worked on the carrier bearing - I'd thought it was unusual at the time but after experiencing some vibration upon acceleration; I only discovered the problem while under the car installing powerflex inserts in the lower engine mount.
Lying on my back, I just happened to look up and noticed the 3 bolts were loose.
Re-torqued the bots - no more vibration.
Loctite next time I'm under there
