G'day everyone, hope we're all well,

I've got a slightly bent rear axle on the drivers side, and the rear brake rotor grinds on the caliper then comes loose and then grinds again when being driven. The dilemma I have now is how to solve it. I spoke to an axle mechanic who said they may be able to bend it back but he wasn't sure how long it would take or how much it would cost to fix so thats a last option resort.

Right now I'm looking for a new rear axle/ 2nd hand axle but need to know the diff ratio (I think I need to at least). The VIN number to the car is YV1244842E6054451, from very quick research I think the ratio is 3.31:1 but happy to be wrong.

Question is, is it worth trying to get a second hand axle from a wrecking Volvo considering how popular they are to put in Holdens and rare to find OR is there someone/somewhere that can make a genuine or aftermarket axle to the same effect.

Any advice would be appreciated (or if someone has a spare axle that fits the bill, I would be happy to take it off your hands!)

The VIN number to the car is YV1244842E6054451

84 = B23E

2 (italic) = M46

E = year model 1984

6 (boldled) = built in OZ

Chassis 054451 puts it in the last 20,000 of the 1984 model to be made (YM 85 starts at #72450). This may be what's known as an 84.5 car.

Doubt very much it's a 3:31 diff, it's more like a 3.54 or a 3:73. You'd have to check the sticker on the diff.

Being YM84 means it should have a type 1031 diff, so you'll want a RH axle out of a 1031 240, but ....hang on - is the whole housing bent, or just the RH axle?

    If nobody has correct one try Berry Motor Group.

    Greg may have one.

      At this stage I think it's the RH axle as its the only side playing up. Left hand side turns fine and doesn't have any of the same issues.

      Where are you located?

      Are you getting massive amount of noise from the rear axle?

      If not, have you checked the RH rear brake rotor for warpage / poor fitting? If the rotor's not sitting flat on the axle flange, it will behave as you describe. And is the caliper mounting true? (i.e. the mounting ears aren't bent?)

      Seems to me like that the axle flange would break from the axle halfshaft before it bent, if the RH rear wheel had copped a massive blow from hitting a gutter or a huge side impact.

      If the housing or halfshaft IS bent, you're better off financially to replace the whole diff sourced from a wreck. The difficulty of getting one will depend on where you're located.

        Its a decent grind on the caliper. For context I had the calipers refurbished with new brake rotors and pads recently, and putting the rear right on was very difficult, both getting it over the rotor and then getting it screwed in. After a short drive less than a KM and checking the rotor, I saw the caliper edge hitting the rotor, chewing both the edge of the caliper and rotor with metal dust to prove it. Nothing extreme to warrant replacing either but enough to not drive the car.

        I'm in the Western Sydney area, previously trying to get parts from the rear axle (panhard bar etc) was essentially impossible so I'm not sure i'll have great chances getting a new axle.

        You might have some luck getting a replacement diff at Lupica Automotive, over at 44 Seton Rd, Moorebank.

        I'm in Castle Hill - I bought a job lot of rear suspensions, including several axles. You are welcome to check them. They are a mix of 244, 144 & 164 axles. I have a complete rear end from a 244 stored in Toongabbie - the rest are in Castle Hill.

        I'm cleaning my garage out so a call will alert me.

        Sadly all my spare cars went to the crusher a month or so ago, so no axles.
