lsd centre swap from 2.92one diff into 3.23 other diff - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

i was wondering if i swap centres myself would i get excessive backlash/whine? the lsd in my ute is very tightand the 3.23 diff is an open centre.
my brother put a mini spool into his cortina diff himself and it upset the meshing of the gears(i didn't watch him so i don't know if he did anything wrong)still worked but was noisy on back off
if theres a good chance it will be fine i'll do it myself otherwise its off to a diff joint.
any ideas/experiences would be appreciated

ps. this is not a ratio change just centre swap open to lsd and vice versa

pps. these are borg warner diffs from a ZJ fairlane and XF falcon, both should have 25 spline axels

Chances are that you will get excessive/not enough backlash, whine or worse if you simply swap the centers without re-shimming everying. This is because there would be slight differences in the centers as well as the diff housings even though they are meant to be the same.

just rang diff mob in melton "proset" and was quoted about $250 to $300ish providing theres no "problems" bearings etc
and in case any one else reading this thread is interested he quoted about the same to tighten up lsd effect on my other ute (XG) providing theres no "problems"
