well im in the process of replacing my clutch and i cant get that damn last exhaust y-pipe bolt out. u know upper one on the pass side. any body have any tips to get this damn thing out. thanks.

 

I used about a 3 foot long extension with my truck on a lift.

 

get a body lift, then you dont have to remove any of the exhaust

 

got this thing is being a pain in the ***. 2 days of soaking in pb blaster and a 150lb impact gun on it and it wont budge. every time i try to break it loose like i did with all the others with a 3 foot breaker bar it pop off because of the wobbly socket. tomorrow im going to try turning it in and out and seeing if that will break it out.

 

I use a weird combination of long extentions, a ratcheting 3/8 breaker bar, a universal, deep 15mm socket. I've been really lucky on my late model Y pipe dropping.....no broken studs. Upon install, I like to brush on a nice heavy layer of anti-seize on the threads full length. That helps next time you've gotta fight it again.

On the back of the Y pipe, where it meets the single pipe, I suggest removing all those studs and using bolts. I now only have to drop the Y-pipe to drop the trans or pull the engine.

The side that you've got the last nut still there...thread on the other nut on the same side of the engine....then try to loosen the stuck nut.



You 3.0's have it nice..... 4.0 it's IMPOSSIBLE to drop the trans without removing the Y pipe. At least the SOHC 4.0...

 

y the flange thing isnt even tight on the bolt so i dont think re-threading in the other side would do any thing. but yea they SUCK

 

150lb impact gun? are you running a 1/4" gun or something? do you have a propane torch? it will not get hot enough to make the bolt red hot but it should help break the bond on any rust and melt away some gasket material. that should help but you will need to heat it for a long time

 

my bad this is the gun...

but it seems that with about every impact ive ever used if u use it to put on lug nuts if u go as tigh as it will go and then go over the nuts with a ft-lb ratchet (cant remember what its called) it puts bolts at about 100ftlbs or so...i cant imagine it tighting a bolt with 425 ftlbs...seem insane..IMO

 

my impact gun would just snap those bolts off at full power. so should yours. and i believe you are talking about a torque wrench

 

yup thats it...brain fart!!!...lol

 

if you can snap the bolts off and drill them out you should be able to put new ones in right? if not you can also snap the head off and use a chisel and hammer and turn it out. if you have the room anyway

 

well i ended up using a die grinder and cutting the bolt....got the y-pipe out and now i got to pull the manifold and the the stud out...o well at least now i can do my clutch.

 

I um... I never removed my exhaust. Tranny came out just fine.

But them I'm 2wd..
