Location: Huntington Beach,CA. | Hiya fellas,
I know this subject has been gone over a few times,but i need a little help.
I got a 57' Coronet which has the ball and trunnion front u joint.I'm trying to rebuild it,but i havent a clue how to get that darn joint pin out! I read past posts about doing away with it completely,and replacing the boot but no advice on how to repair the u joint itself. Can i remove the pin with some average tools or would i have to take it in to a shop?
Thanks~ |

I have also gotten them out with a large C-Clamp and a deep socket. Make sure you have sufficient depth in your tube you use for the receiver of the pin.

Every one I've dealt with would laugh at a heavy duty arbor press, even my 20-ton hydraulic press groans to press out the pin.
The trick to centering the pin is good lube and an accurate stop. |

Hmmmm...
I removed the one from my Adventurer B&T in my garage (NO arbor press there) with a big U-Joint press and anvil set!
Maybe mine was at the loose end of the clearance table.
Mind you, a U-Joint Anvil/Vise set (Snap-On) is a pretty robust tool, with a HUGE fine thread srew and requires like a 1" socket to fit the head, so it is more than the average bear of a C-Clamp......
BTW...I do agree about reinstalling, in that centering the pin is a B*TCH! So I had a tool machined that only allows me to press it to the correct depth....

Location: Blythewood, SC | I guess I'm lucky. I got mine centered on the first shot with a 12 ton press. |

Works unless you are using a *NEW* pin, like I generally do...... |

Location: Huntington Beach,CA. | That sounds like a good idea,my original seems fine.
Heres the kicker though, the kit i bought from Bernbaum looked fine until i tried to put the bearings on the pin....they don't fit! Both the new and the old pins seem the same, but i think the needle bearings are different sizes! Did they use two different sizes , or is this Bernbaum dude not only selling crappy u-joint boots,but also junk kits??
Thanks for the reply  |

I think i'll leave the pin in,and just stick the new bearings on ...if only they would fit! Bernbaum strikes again!ARG!
Thanks for da help~

Location: Blythewood, SC | I would guess you are another Bernbaum victim.
Just for reference, I bought a complete kit with a new housing off E-Gag for $50. Of course, I ruined the boot and modified a CV joint boot to seal it, but it's working just peachy.

There is more than one kit for the Detroit B&Ts...Mine is the larger "57" series, not the smaller.
So you need to do the following with Bernbaum....
Measure the bolt spacing on the housing, call Bernbaum, and give that to ANDY....
He will then get you the correct kit (large or small) |
