Mercury Repair Questions? Ask a Mechanic for Answers ASAP
Thanks for coming to Just Answer to ask a question.
Did you just replace the differential or the complete axle assembly?
Either the differntial was not set up correct meaning the backlash and bearing preload is not correct.
Or all 4 tires are not the same brand and size and tread depth and the AWD is fighting itselff front to rear.
Or you need to install a S spring between the spider gears to prevent tehm from being loose in turns.
You check backlash witha dial indicator.
If you have the wrong gear aratio then hte front and rear axles are not turning teh same speed and this will cause numerous part fialures i nthe driveline.
the dealership told us our gear ratio was 355 how can I find out what the gear ratio is on the front differential we installed. Where is the tag and what should it say to be a 355.
We are pretty sure we got the right ratio but we will check that and the s spring and the rear ring backlash. Thanks for all your help! It's been driving us nuts!
