whats the issue with jacking on the diff..
its the most securely fastened part of the transmission
and id be utterly amazed if you were able to damage the unit by jacking on it, considering its a very thick cast steel part
the Lexus workshop manual, states that that is the rear jacking point, so, in your opinion why is it not a good idea?
Why would you wish to use any part of the transmission as a jacking point ?
The handbook for my Series 1 GS300 and also the handbook for my Series 2 GS430 both state quite clearly that you should use the jacking points that are on the car, in front of rear wheels and behind front wheels by the area of the sills. Whilst I realise that a lot of people do use the diff as a jacking point I am at a loss as to why, when the manufacturers provide strengthened positions for jacking.
I cannot find anywhere in the Lexus handbook for my car that states that it is the rear jacking point although the illustrations in the DIY section are somewhat unclear but does state "make sure to set the jack properly in the jack point."
