Diffs:
- 1031 open in 240 wagon, quiet, has good heavy synth in it
- 10?1 open in 740 sedan, slight whine has developed after many many burnouts on probably very old oil
- 1041 Eaton G80 locker in caravan, low mileage (140kkm?), quiet worked fine, did skids
- 1041 Eaton G80 locker on bench, looks OK, clean oil, have not driven, do not know, damaged brake backing plates, relatively new overall
- 1031 probably-open in parts 240 sedan, no idea of condition, or ratio, but probably useful for whole-axle-swap style work.
- G80 in the 240 for wet traction and more controllable slides in the wet - skids not an option, insufficient power, excess weight
- G80 in the 740 for skids and traction and controllable slides in the dry or wet - skids an option, sufficient power, acceptable weight
- Light, compact, diff-less axle with full brakes in the caravan
- Spare 740 housing, diff, etc ready to swap in when I break the 740 diff :-D This will happen, it's just a matter of time. If I end up with this being another G80 later, great, but anything would do to keep it on the road.
- Spare 240 housing, diff, etc ready to swap in if I end up breaking the 240 diff. Just in case, as it'll eventually get a double or triple power increase with DOHC turbo.
Well, I think the best thing to do is to prepare the diff-less axle for the caravan using the
G80 that's on the bench as a base. Remove the G80 core, and the ring and pinion, etc.
Figure out how to support the spline ends of the axle to make the load bearing capability
of it safe. Then swap that in to reduce towing and unsprung weight, and shift the balance
slightly further back (diff head mostly sticks forward of axle).
Out of the caravan will come a complete and happy working G80 axle with good brakes
to go into the 740 sedan. Swap this into the 740 sedan as a unit, while removing the
existing noisy open diff as a unit to keep as a spare. Take the brakes from this and apply
them to the caravan again so it's handbrakeable again.
Which leaves me with a G80 core, an open diffed 240, and a spare entire 240 diff to play
around with. So, get the spare 240 diff on the bench and carefully swap in the G80 core.
Then swap the whole axle into the 240 wagon one sunny day.
Anyway, I made a little progress on this tonight, so here's a few pics for the new thread:
