Could do with some help regarding my rebuild project. Currently have the IRS in a thousand pieces and while I have majority of parts needed to rebuild, I am short of a few parts for the Power Lock LSD. Unfortunately, this is holding-up the diff set-up and the entire IRS reassembly.
When I opened the diff, the oil was very gritty and had badly pitted the ring and pinion gears so I have purchased new (swapping the 3.54 for the 3.07) and all new bearings, etc. Unfortunately, when I opened the LSD the internal gears are not so great either. Basically, I would like to replace many of the internal parts. I have new clutch plates and two of the four pinion bevel mate gears (other two on back order with SNG) but I would also like to source the side gears and the ring for side gears (items 5 and 6 on the attached diagram). SNG says the parts are no longer available. Not comfortable replacing only a few of the mating parts.
For reference, I took a photo of my LSD markings to help identify type. I have read so many times the Jag uses the Dana 44 diff but have not seen any guidance on whether the Power Lock LSD is common to other vehicles which might help the search for alternate sources.
Take the parts you need to a four by four repair shop and discuss it with them. Dana 44’s are common in Jeeps etc and they should know what is available and from whom.
You could also contact these guys. They have been in business for years, and if they don’t know I suspect it isn’t knowable
I got a pumpkin for a 3.8 etype. My project came with one like yours sounded like. Abused and run low on oil. Clutch plates broken, splines shaft ends worn bad. The salvage one from welsh was in great shape.
