how strong are the stock trunions?

Having a heck of a time getting the bushings/sleeves/bolt out of the drivers side trunion. I have it off the vehicle on the bench. I've soaked it in WD40 and then with the castle nut on the threads to protect the end, I've put a 13/16" impact socket over the head and tried pushing out the sleeves/bushes with a vice. It's NOT moving. Even tried tapping it lightly with a ball pean hammer or whacking the vice with the 5lbs hammer to loosen the rust between the trunion bolt and the sleeves around the bushing but they're not coming loose.

I'm letting it soak over night in WD40 before I try to press it out again tomorrow, but I'm wondering how strong that cast trunion piece is? If I'm too vicious with the vice, am I likely to break it?

Don't like the cost of new ones from Moss....looking at what winners circle charges for offset ones....
 
Rob, First thing is toss the WD, and go buy a can of PB Blaster. there is no substitute for the stuff. Have you tried a little heat? Careful with this as most likely the old rubber will burn quite nicely, especially if soaked in WD or the PB. The upside is that if you burn out the old rubber you may be able to get a drift in there to punch them out. AHh the bolt is still in there.. you may have to drill the whole mess out. and if it is that rusted together new ones may not be such a bad idea.....

I think I understand what you're doing...

Generally, I drill out the rubber as much as I can and then burn out the rubber bushing. Then remove the bolt and grind the stock sleeve off the bolt (carefully).
 
cool, sounds like I get to play with some PB blaster and the torch this morning /ubbthreads/images/graemlins/wink.gif
 
remove the bolt with the metal part of the bushing stuck to it, then take a deep socket that fits, stand the bolt on end and then pound on the socket to knock the bushing off the end of the bolt....do this on a log etc. so u dont flatten ur threads like i did.......zimmmmy
 
ps. u might need to squish one of the bushings with pliers if its still stuck in the trunnion...then pull it thru and do the above.........horrible job aint it? ive got one new shock.....and the other side has 1 broke bolt, 1 stuck bolt, and 1 that comes right out! rrrrrrrrrrr ; )

This is basically what I did though I used the vice instead of a hammer. BTW, if you leave the castle nut on the end of the threads, they won't flatten out /ubbthreads/images/graemlins/cool.gif


Managed to get it all free after about two hours of fiddling this morning. Just took a lot of time with a low-heat torch, penetrating oil and a couple of sockets...I managed to break one sleeve loose about 1/16" and then the other sleeve popped 1/8" and from then I just had to keep tapping them back and forth adding penetrating oil until they were completely off.

I started reassembly but got hung up with reinstalling the springs and my modified front tube shock conversion. I picked up some new hardware and the aluminum spacers are 0.25" longer than the old steel ones, which suddenly made my 3" long bolts 0.25" too short, so I've ordered some 5/16-24x3.5" grade-8 bolts from McMaster. I'll finish putting it back together later this week....
