I recently had to remove the rear differential in one of my cars to replace a bushing. It is IRS, so a differential with flanges w/ 6 bolts each for all rotating connections. I was considering using blue loctite on all the bolts, for an additional safety margin over the 82-130lb/ft (depending on the bolt) torque spec.
To get the differential out, I also had to remove the rear sway bar, the exhaust pipes and muffler, drop the driveshaft center support bearing, etc. I was considering using blue loctite in all these positions.
Would it be a bad idea to use loctite? My concerns are the loctite possibly acting as lube and causing overtorque, or preventing disassembly. Some of the OE 82 ft/lb bolts required heroic measures to remove - but they have been in place for 10 years.
