Diff Drop Brackets

I think all said and done I paid $50

"I think all said and done I paid $50"

OK, let us in on your little secret. Did you buy em or make em? Joe indicates $200 plus shipping & my welder is estimating $150 plus shipping.

bought the brackets from someone parting theirs out and got a welder to fab it basically free.... Its not that hard of a job, but I am no welder either, just what I have heard.

'Bout what I figured. You owe your welder friend about $100 in favors I prolly could've done the same but I was trying to get it set up to help others out. Rekin humanitarians never get rich

BTW - you have to go back to page 4 of this thread to find out why it got bumped.

Not sure where the bump took place.


$100 yeah right. Its no more than an hour of work.

Ida know. I'm not a welder. He fab'd inserts, then cut out a section & welded in the new. Since he prefab'd the inserts, maybe he had to take the time to ensure alignment. I think he said that he used 7 welding rods since he welded both sides. Since Joe charges $200, I don't think this guy is too far off.

The alignment issue does bring to mind one thing I was curious about: since we are dropping the diff to ease the CV angle at the expense of U-joint angle - would it have made sense to rotate the mounting features on the bracket to relieve some of the angle we are imposing on the U-joint?

The comment on the bump was just to let others know to look back a page to see why this thread became active again after several weeks.

I am more or less guessing on this one based on things I have heard and read over the years... I wonder if rotating the housing would throw the joints on the driveshaft out of alignment, causing vibration. In stock form, the joints on the shaft are at equal angles; of course even with dropped brackets the joints are at equal angles. After rotating the axle housing in order to position the pinion closer to it's stock location though, the angles would no longer be equal, so they may not "phase" during rotation anymore - causing vibration. Like I said, just a guess... people shim the rear axle after adding a lift to leaf sprung rigs to minimize driveshaft angle. Screw it!

1/3 the way down talks about all this, maybe it will help explain.
