      Transmission? No, it's the RF axle!

      In the '07 V70 T5 FWD w/ 305,000mi, my son drove three miles from the house and stopped at a red light. Shortly after, he called from his cell phone and related the following: When he pressed on the accelerator, he heard a clunk and the engine raced and the car would not move. He moved the shifter into neutral and heard a quick grinding then nothing. A police car pushed the car with the shifter at N and the car did move easily, and even drifted a bit after the police car stopped pushing. The AAA tow truck will be carrying it to my independent Volvo mechanic very shortly.

      What might it be? I'm thinking shift linkage is at fault. I'm wrong on both points. See below.

      CV axle broke or popped out of transmission or transmission itself is gone.

      I should add that there's been no transmission noise or loose drivetrain until this, and the car was serviced one week ago for routine 5,000 mi. oil/filter and overall vehicle inspection by Volvo mechanic.

      Something broke. Visual inspection of the driveline should identify or rule out axles quickly.

      They canít look at it today, but Iím dropping it off, one mechanic said he bet it is the axle.

      Iíve had axles replaced at least twice over the past 250,000 miles, and I opted for aftermarket rather than genuine Volvo, betting the car would not last as long as the axle. Maybe I was wrong. Iíll know more soon enough.

      The loaner is an 850 four-door sedan with 260,000 miles and studded snow tires for this afternoonĎs forecast snow storm.

      Yup probably broke an axle in the trans. The turbo cars twist and snap aftermarket axles. Used OEM is the only way to go. Get one from Erie, itís the same any 2.5T fwd or T5 auto.

      The passenger axle may have its carriage bearing slipped from its place, the splines then may quit the differential, thus the grinding sound and no power to the other wheel.

      Also axles for the different models have a slightly different length that may not be accounted by aftermarket vendors. If your aftermarket axle was a bit too short, it may have stripped the splines, on the axles and/or in the differential.

      New (refurb) GKN axle!

      Axle is the same length on the inside of the CVs for 5 cylinders. Outside changes.

      AWD and FWD are different.

      Also the axle is aftermarket as was said.

      Diagnosis came in quickly: On the right axle, the axle's weld where it holds the bearing failed. It's not the usual CV joint failure.

      This aftermarket axle lasted only about 26,000 miles! So, I specified the Volvo OEM axle this time around, a substantial price difference. At least I get a $110 credit under a pro-rated warranty. My mechanic believes it comes from China. I admit, the shop always was clear about the choice, the price difference and the risk.

      The left side was replaced with one of those aftermarket axles 165,000 miles ago. It's been inspected during this service, and it appears to be okay. But my understanding is in this year and model FWD Volvo, pulling away from a stop on a dry paved road puts all torque onto the right axle, perhaps reducing concern about the left aftermarket axle.

      Get GKN axle at FCP, the price is not bad at all, plus FCP has a lifetime warranty.

      Torque goes more to the left wheel. This is apparent on a AWD Volvo that has broken Haldex or stripped collar sleeve, the torque steer to the right side is tremendous.

      Torque transfers to whatever wheel is less loaded. Open diff.

      I have a quaife LSD and it puts the power to whatever wheel is more loaded. Completely changes the driving experience.

      The torque steer is created by wheel rotation, volvos use equal length half shafts.

      Torque steer is created by the difference in forces at the contact patch between wheel and road. Driver side axle is shorter and transfers more torque to the wheel, while the passenger axle is 2+ times longer and "steals" some torque by slightly twisting itself. I didn't feel it on my FWD V70, but XC70 with broken AWD is just mad.

      You know that passenger side carrier bearing? Thatís there so the half shafts are equal. The distance from the inner CV to outer CV is the same each side. That carrier shaft from trans to carrier bearing doesnít contribute to effective axle length.

      The XC experiences way worse FWD driving dynamics because of its engine tuning relying on awd for traction as well as suspension. If you turn off DSTC in a fwd car itíll drive just the same.

      Science mechanics of materials disagrees, that bearing does not do anything to torque. It's not even a part of power flow.

      Exactly. Less torque to front wheels, since it is distributed across all four at start.

      The engine is not making the kind of power to plastically deform the layshaft axle tube below itís endurance limit to the point of causing meaningful torque difference. Just not happening.

      What Iím trying to alert attention to is that the layout of the CV positioning and the use of the layshaft are to prevent the unequal axle length situation.

      Alignment fluctuation causes what it classically called torque steer but is not.

      Anyway the point here is to further the cause of the community. Issue seems to be a defective aftermarket axle; solution being replacement with genuine or equivalent axles for fitment, strength and longevity.

      OP get an alignment post axle replacement you need it anyway.
