I just had my Subaru Outback's oil changed at 32,000. They recommended at 30,000 the front and/or rear differential fluid should be changed. I believe that it true and I asked them to do it. They said they could not find a rear differential. Then they said they couldn't find the plug for the front differential. Is the dealer trying to get business at dealer service center only by hiding these? I have confidence in where I took the car and I know they will be cheaper to have it done. What's up with this?

Answers from the Automotive Experts

Amy Mattinat, Owner and Author at Auto Craftsmen Ltd Hi Kathleen, Yes the differential fluid can be changed. I recommend finding an experienced Subaru technician to do the repair and service on your Subaru.

Barb Petrey, President - DBK Enterprises Inc at Jiffy Lube Is it a 4WD car? If not then you only have a front differential. The front differential and transmission share a common unit if it's manual transmission. If it's an automatic there should be a drain plug as well as a fill plug . Make sure you open the fill plug first. A rear differential , the fill and drain plugs are on the backside and it's a tight area to work in.

Helaine Kurot, Owner/Technician at 360 Automotive Suburu does recommend changing the fluids on the front and rear diff at 30,000. This vehicle takes very specific fluid for the differentials. You may be better off going to the dealer or a transmission shop for this service.
