92loyale59 Posted January 1, 2014 Share Posted January 1, 2014 so i looked in the search forum and found a little bit of help on this subject but not much. i was wondering what the best way to replace the pinion seal on the rear diff off a 92 loyale . i remove the driveline from that end ans tried using a breaker bar to break the big 27 mm bolt loose while the tires were still on the ground but no luck . do i need a impact gun to remove it ?? thanks in advance for any help Quote Link to comment Share on other sites More sharing options...
MilesFox Posted January 1, 2014 Share Posted January 1, 2014 maybe place a jack under a breker bar? The one time i tried to replace a pinion seal, i was unsuccessful. I went as far as trying to drive the cr so that the pinion nut would rotate gainst the breaker bar against the ground. no luck. Quote Link to comment Share on other sites More sharing options...
el_freddo Posted January 2, 2014 Share Posted January 2, 2014 I did mine with a rattle/impact gun to do the job. It took some time to get it off even with the rattle gun. Once the nut was off I remember the flange coming off easily. I used the rattle gun to put it back on. CheersBennie Quote Link to comment Share on other sites More sharing options...
92loyale59 Posted January 2, 2014 Author Share Posted January 2, 2014 thanks a lot . i tried a huge breaker bar and the nut would just move along with the wheels even though i had them blocked up. i guess i will try to find someone with a large enough compressor so it can actually power my impact gun Quote Link to comment Share on other sites More sharing options...
robm Posted January 2, 2014 Share Posted January 2, 2014 Try having someone put their foot on the brakes, HARD! Then use the breaker bar and a piece if pipe. Quote Link to comment Share on other sites More sharing options...
odie Posted January 2, 2014 Share Posted January 2, 2014 bigger breaker bar...I got a 2 footer for tough nuts...but a high quality impact gun is probably your best bet... Quote Link to comment Share on other sites More sharing options...
idosubaru Posted January 2, 2014 Share Posted January 2, 2014 if you have some large flat steel of some sort - you can drill two holes in it and bolt it to the flange the driveshaft bolts to - this will then provide a lever arm to lock the diff/wheels in place so they can't turn while you're messing with that nut.

92loyale59 Posted January 7, 2014 Author Share Posted January 7, 2014 so i ended up makking this tool to hold the diff in place while i used a breaker bar to remove th 27 mm nut it worked but i did end up bending the tool some . i parked my car facing up hill so i wouldnt have to drain the diff fluid since its all ready new .once i removed the 27 mm nut i tapped off the coupler or whatever it is and then drilled a small pilot hole in the seal and drilled a long wood screw a bit into it . then i pried on the seal and out i came . greased up the new seal tapped it in and tapped the coupler back on then i put lock tight on the threads and tightened it back up to where it was ( i made i mark with a chisel) . now theres no leak . thanks for the advice evryone Quote Link to comment Share on other sites More sharing options...
