3084v half-shafts --cant get them off

I am just about to reinstall mine on my Mondial, same as yours. The bolts were very tight. They actually sparked when they came loose. Make sure you use a quality, snapon/mac allen head. On one shaft, the Mac allen lasted for 10 bolts and 45min. THe last two took 2 inferior allens and 2hours. I did have to cut one nut off with a Dremel tool. Went pretty easy. You will have to get new nuts/bolts from the dealer. ABout $7 each. Go easy and have lots of cut off wheels for your dremel.

I use a good quality 3/8 allen drive socket, a 1/2 - 3/8 reducer and my torque wrench (longest/highest leverage) after a few dosings with PB Blaster. They will come, but yes, can be a challenge. Lots of skinned knuckles on this particular job if I recall.

There's a reason why servicing costs on 308s are so high. (Packaging).
Good luck.

 

I used a Craftsman allen 3/8" drive with my butterfly air wrench. Soaked both the head & ends of the threads them for a couple of days with PB Blaster 2x/day first. Think I may have had to use a 3/8" breaker bar on a couple of them.

They were really torqued down. Not sure if they'd have broken loose w/o pre-soaking with the PB Blaster penetrant.

BTW, my car is very clean in general, so they weren't rusted, just really tight.

 

Try this: put the wheels back on the car and tighten them down. With your rachet or breaker bar braced agianst the frame , grab a hold of the wheel with both hands and turn it in the appropriate direction. 9 times out of ten they will break free with this method. If not a little bit of heat on your nuts also works. You don't need too much, no need to get them cherry red.

I have found that a heavy-duty impact wrench (1/2 inch) works the best...........after soaking for a while in the Blaster. The quick on-off power of the impact wrench seems to work better than the steady pull of a breaker bar.........for me, anyway.

 

I have done this too many times. They always come off no problem with an impact wrench. You can't work of 4re's without one. Allternatively spray wd40 on nut and heat with torch. Then it will come off guarnateed

 

1) do you have a good impact gun?
2) don't soak.
3) wd4- torch to draw into nut impact off
4) strip hex head then slot with a diegrinder and impact screw driver off
5) heat nut with torch air cool to anneal. cold chisel nut to split it and air tool it off.

 

I did the shafts on my 84 Mondial recently, as it happened I did not have much trouble getting the things undone but a specialist advised me to use a cold chisel on the nuts if they would not move.
I think if the problem persists I would cut them off.

 

been there, done this. On my old 308 they were TIGHT!
I used a long extension and a LONG breaker bar, (about 5 feet!). The POP noise was UGLY, when each came off. I actually BROKE a few of the hardened bolts! I also had to CUT three of them off with dremel tool. I also destroyed a husky socket, use a snap-on or craftsman.
Listen, plan on buying NEW bolts and nuts anyway. Just BREAK them loose or cut them off. Then replace them with new ones.
This will work.
