I have a 2003 Santa Fe. It is the AWD 2.7L engine, GLS version and has recently passed 60,000 miles. I have had the timing belt changed and the various other required service items taken care of, however there is something in the maintenance schedule in the manual that I have a question about.
There is an entry referencing the "rear axle oil". Most intervals are just "inspect", but a footnote states that with an "LSD" (I assume that's "limited slip differential") the rear axle oil should be replaced at 40,000 miles (this has not been done)
I have some questions about this.
From Edmunds.com, the standard features of the Santa Fe GLS AWD lists "limited slip differential (center)". Is that what is referred in the manual as "LSD"? I guess I was wondering that since the features specifically mentions "center", but the service manual talks about the "rear axle" oil, is the "limited slip differential (center)" the "LSD" referenced in the service chart?
In various web locations (including the dealer's web site) I see references to the "differential service", or "changing the differential oil". Is this the same service listed in the manual as "change rear axle oil"? The dealer price for this is about $80, but I have a coupon for $40 off "any service or parts", so I would imagine $40 for the job wouldn't be a bad price for this.
I'm not experiencing any problems, but assuming the "change rear axle oil" requirement applies to my car, have I done any serious damage by not having it done by now?
Thanks Mike O.
