I am in the process of tring to change the Knock Sensor. I have all the right tool but I just can't get the bolt on that SOB to break loose. Is there any secrets to this ,please help I want to get this done. I have followed all the directions on all the sight that tell you how to do it,so it isn't that I haven't read up on this. Anything will be appreciated,thanks!

 

oh man let the flaming begin

 

Try soaking it with some WD-40, or better yet PB Blaster. This usually eats away at corrosion and lubes the threads by seeping into them so you can take the bolt of easily

 

Some swivel sockets (especially cheap ones) bind up very easily, and will break if cranked on very hard at a tight angle.

The best ones to use are not the ones with the square piece in the middle, but the black 'impact' swivel sockets. These have a slot that a 'pin' drives through. These work the best at extreme angles. (like a knock sensor on a Maxima)

If you are trying to use a regular 3/8" drive socket on a swivel extension, it probably won't work. This puts everything up too high, and puts the swivel in a bind. You might get by with this using a short 12mm 1/4" drive socket and swivel extension, but not 3/8" drive. Using 3/8" drive tools, you'll need an actual 12mm swivel socket. (preferably pin drive)

With a little care, I was able to use a 1/4" drive short 12mm socket and 1/4" drive swivel to do mine.

Good Luck!

 

I tried the 1/4 " swivel socket (Sears) but it did not work for me. The bolt would not budge. Eventually, I used a regular socket wrench to break loose the bolt first, then take it out using the swivel socket.

there are detailed directions on there, and you better have a magnetic pickup or SMALLLLLLLLL hands

 

^^^^^^
That didn't make much sense.

But anyway thanks for the replys. I used the tools from sears like skippynet
said to use. I guess I posted this to soon b/c after I posted it I went outside and tried it one more time. I am not a wimpy guy by any means but it took all I had to get that bolt loose. I had to turn that wratchet very very hard. When the bolt came loose I thought I had broken something. But when it did come loose I had some bloody knuckles.

So for reference you can do it with a 1/4in wratchet 14in extention and that 12mm swivle bolt like other have stated but, you have to turn that thing like a SOB and it will eventually come loose.

 

The girlfriend supplied the small hands.

 

heheh cool... I used a magnetic pickup..I'm 6'6'' with size 15 ft and hands of a comparable size, so without that pickup i was screwed.
If you ever run into that again, get a pipe or something long and hollow, and put it on the ratchet handle and use it for leverage...i should have said this earlier, must've been a brainfart... Glad you got it done man! Now drive the car! YOU WILL LOVE IT
