Alright, so this is a weird issue I've been having intermittently in the past couple months.

Sometimes when I accelerate forward under light throttle it feels as though the rear end isn't catching. It's not a slipping feeling like no traction, but more staccato. I can only think of two things:

1. Is that the brakes aren't disengaging and it takes some forward momentum to break them free. Doubt this because brake travel is fine and I have no issues under heavy braking.

2. That something is up in my rear-end and the gears aren't catching. I think this is probably it. Given the sporadic nature of it, it makes me think that I may have a tooth or two missing from a section of one of the gears.

Anyone have any ideas?

Do you have two of the same tires on the back? Are both your tire pressures in the back the same?

ilamir

Yep, same brand, pressure and tread depth.

Have you ever changed the differential fluid? Try your test with the traction control off.

ilamir

Haven't changed the diff fluid yet, planning on it in a month or so.

Will do on the test w/ traction control off.

Where are you planning to change the diff fluid? Yourself? Reason I ask is you can join www.mscw.com and do it on a lift at a tech session.

Have you seen the DIY thread on doing this? - very informative. You can also do you change out your manual transmission fluid at the same tech session.

I recommend and use Red Line Oil products available down the street from you at Rosenthal Mazda Arlington. Read the DIY - you'll want to get new crush washers too.

I was definitely planning on doing it myself. I've also read through the DIY for the 8 so I was going to do both the diff and the tranny fluid at the same time.

When are your tech sessions? Checked out the site and the date says TBD.

We have one scheduled for June 16th in Gaithersburg @ Gaithersburg Mazda. We're planning to have one in August/September, I think, at Rosenthal Mazda Tysons Corner. I'll PM you in a few days with details I scour up on the Aug/Sep sessions.

You must be a paid MSCW member to participate - $27 to join for 1 year and $5/per tech session includes use of lift + dinner ...... cannot beat this deal. Membership gets you parts and service discounts and various dealers and other shops. See http://www.mscw.com/benefits.html to apply/pay/join.
