Rear Diff Q for 320i coupe 1994/M
[alt.autos.bmw,uk.rec.cars.misc]
I'm in the process of sourcing a rear diff for a 320i coupe (This was the cause of the vibration in the rear wheels I posted a while back). One chap has rung back and asked if its the one with 4 or 6 bolts in the retaining ring. None of the other suppliers (that quoted a price) have asked this. So either this chap really knows his stuff or he is asking a slightly pointless question. Given the make and model is it really likely it comes with two different types of retaining ring? Also my garage are getting a price for sending it away for a rebuild of the rear diff? On this age of car that seems like a complete waste of cash to me? I'm not sure why they are exploring this option at all. Still they will install a used rear diff if I can get one. Lordy |

Most gearbox and diff rebuilders just mix and match secondhand bits from stuff they get at the scrap yards anyway. |

I'd have the rebuild if it's not too expensive, as that way you will get a known good diff with a 'warrenty'. This is the route I took with the 75's gearbox - it needed diff bearings and synchro rings. Rather than risk a used box doing the same thing in a few thousand miles, I decided a proper rebuild was the way to go. Even if it did cost me 400 sheets. -- Steve H 'You're not a real petrolhead unless you've owned an Alfa Romeo' http://www.italiancar.co.uk - Honda VFR800 - MZ ETZ300 VW Golf GL Cabrio - Alfa 75 TS - VW Passat 1.8T 20V SE - COSOC KOTL BoTAFOT #87 - BoTAFOF #18 - MRO # - UKRMSBC #7 - Apostle #2 - YTC # |

I only paid £120 more for a gearbox rebuild..... ie. not just the simple bit, all the synchros and replacement of some of the bearings in the gearbox bit of the transaxle. Plus I got a 6 month warranty. I think you need to shop around for the rebuild personally, as £280 is a lot to risk on a part that may or may not still work in 5k miles time. I've been burned on this before with a gearbox for my Alfa 33. Replacement went the same way as the original within 6 months. -- Steve H 'You're not a real petrolhead unless you've owned an Alfa Romeo' http://www.italiancar.co.uk - Honda VFR800 - MZ ETZ300 VW Golf GL Cabrio - Alfa 75 TS - VW Passat 1.8T 20V SE - COSOC KOTL BoTAFOT #87 - BoTAFOF #18 - MRO # - UKRMSBC #7 - Apostle #2 - YTC # |

I'm not aware that diffs are a weak point so your gamble may pay off.
I replaced a gearbox for <200 quid not that long ago but the labour cost was my own. A diff should be a piece of cake. |

Garage charged 80quid (inc VAT) Labour. Tow (from Rip-Off Garage to Cheap one) was 25 quid. Grand total 245 GBP. It would have been only 220UKP if the car was initially recovered to the cheaper garage in the first place. Highest quote - Brand Shiny New Diff (940 inc VAT) + Labour (352.50 inc VAT) = 1,292 GBP Lordy |
