Is there a seal driver out there for the two front differential seals? I could get a single driver or a kit if recommended by anyone. I'm planning on doing OPG in the spring and want to have all the tools to do this job right and minimize time and failure.

Last time I did CV axles, I used a 2 inch PVC pipe which wasn't ideal.

the old seal and a rubber mallet? Should take 20 seconds a side

That's such a crazy idea it might just work! thanks!

Honestly Just did it a month ago for the exact same seal/job and 20+ years prior. Its the proper size and most are rubber lines so shouldnt marr the seal.

Just line it up straight and alternate sizes to get it in straight

I've done CV axles and seals last year and used a PVC pipe as a driver. It was slightly too big for the seal and was difficult to drive straight. I periodically check for leaking fluid, it's been good so far. I don't think the seal does anything for preventing fluid from leaking out from the way it lightly sits on the CV axle. More like Prevents dust/water/grime from getting in. Maybe if you overfill the diff fluid, it will start leaking since the drain plug sits slightly lower than the output shafts. Diff fluid gets pulled up and clings to the differential gears as you drive.

Not excited for OPG in the spring. At least I know the subframe was lowered and suspension components replaced at some point during the life of the vehicle. Not expecting seized or problem bolts.
