Engine Mechanical problem
2006 Acura RSX 4 cyl Front Wheel Drive Manual 20000 miles
----------------------------------------------------------------
I cannot seem to budge my port wheel nut (holds the hub to the axel / drive shaft). I have tried both directions. I use a 4 foot bar and weigh nearly 250
myself. This doesn' t seem right.

Are the port side nuts 'reverse threaded'? Any ideas
on how to break it loose? I have a 550 foot pound
impact wrench and it won't do it either!

thanks,
ward

are you first of all doing this with the wheel on and the vehicle on the ground? it is counterclockwise, at least all the vehicles ive ever done this to is, to loosen so its regular thread, are you sure the cotter pin is removed from it and its not snapped off in it? soak it with penetrating oil also if possible heat it up with a torch, but make sure everything is disconnected first...and only use it if the penetrating oil and a longer bar doesn't work.

im surprised your 550 ftlb impact cant loosen it!

usually they loosen right up for me with a 3 foot breaker bar.

check the threads just in case it is clockwise thread, put a needle on the threads and go around it counter clockwise, if it loosens then its a regular thread, if it tightens then its opposite threaded.

Yep, I'm doing it with the wheel on the ground.
I just broke my 1/2 socket drive.... must be pretty
stuck!

The penetrating oil hasn't made any difference. I let it soak for a couple hours.

How much heat might this need? I only have a MAP gas tourch... I doubt that'll heat it enough.

I'm pretty certain it is a left handed thread. I guess I can go to the dealer and buy the nut and see that way. There isn't much thread showing past the end of the nut."

if i recall right it requires 500 foot pounds of torque to loosen then, are you using a 6 point IMAPACT socket to loosen it? i use a 3 foot breaker bar that i use on my home tractor with a really thick walled socket, and on the end of that i attatch another long pipe for leverage, it bends but it shouldnt snap on you.

try running your impact at a higher pressure.

maybe find a way to get a house jack to sit on it and pull up on it. if thers a semi truck repair shop near you anywhere, take it there and have them break it off for ya, then tighten it down get her home and reloosen. they are on there TOUGH

I finaly got my wheel nut off. I had to grind away one side of the nut and sacraficed the shaft. I'll have to replace it but such is life. Even after grinding half the nut away I broke my 1/2 socket drive AND my 1/2 inch breaker bar. Then I used an air hammer and a chisel and loosed up the remaining fraction of a nut. Turns out the previous mechanic had used thread cement.

When I spoke to him he said, "No one in my garage would ever use anything like that on a wheel nut. You must have had subsequent work done somewhere else."

Yet another reason to always do one's own work if at all possible.


Grrrrrrrrrr

the guy that did that was a moron, never heard of that to hold on the wheel nut, they are torqued on and a cotter pin hold it on anyways!

sorry to hear you had to sacrifice the shaft, and the 1/2 socket and breaker bar!

and THANK YOU VERY MUCH for the donation!

Oh.... no problem with the tools, its why I always
buy craftsman. I may break them more often BUT
the break is always temporary!

THanks for your help. Nice service you're providing,
happy to support it.
