I did all the front diff bushes at 90,000, seems like yesterday 2-3 years ago.
Dropped the diff myself with very basic tools
Now at 166,000 the very front one looks 70% gone easy to replace in 30 minutes and $130.00

Fingers crossed replacing the front one early might save the diff mount under the drivers seat, and the rear CV joint on the front driveshaft another 50,000 plus to get me to about 225,000 and the 2nd set is gone.
