I'm not sure what it sounds like. You haven't ran anyone over lately have you?? Maybe you are dragging a body?? :biggrin:

Now I'm thinking it might be my rear wheel bearings. Im gonna check them out this weekend if I have the time.

Or maybe I'll find a body under there.................

the differential will grind/chatter when going around turns. you could always swap the fluid and check for metal bits (easy, and reccommended)

it could also be a wheel bearing or cv joint. i think the rear bearing is easy to replace, and the front one is difficult. it could be the other way around though.

depends on what part of the diff is failing. ring and pinion will whine - noticeably changes under load and with different speed. do you have an open or limited slip diff? i would check the fluid level for sure and change it if you haven't for a good while.

thought the front wheel bearings were sealed. therefore the rears should be changeable. check realoem.com to see if the replacement parts are available.

It turns out that I need to replace my CV joints. Does anyone know a good place to buy them for a reasonable price? I found them for 130.00 a piece at a local shop.

is that for the cv joints or the whole halfshaft? never replaced a cv joint before so i don't know how much work that is. you could probably get used halfshafts for less than that (but of course you don't know how much mileage is on them typically). bmw rebuilt halfshafts will likely be around $260 each.

Its 130 for a rebuilt halfshaft. I thought that was a pretty good price.

So I am stressed the **** out. The place I originally ordered the half shafts didn't have them in their warehouse, their computers said they did but they weren’t actually in their warehouse. So My dad called up Bavarian Engine Exchange last week, they had them and said they would be delivered within 7 business days. I called them today and they haven’t even shipped them and they said they will ship sometime next week. That place ****ing sucks ass. Does anyone else know of a place that has rebuilt half shafts? I really need to get my car back on the road this weekend. Though that is most likely impossible at this point.

I've been driving my stepfathers 93 VW Passat that has 234,500 mile on it. The problem is that I commute 160 miles a day and I don't want to drive the Passat more than I have to. Plus he has to have my mom drive him to work everyday and I’m sure that is getting old.

PLEASE HELP ME!

you may also want to consider the bmw dealer themselves. my old mechanic said he wouldn't get reman'd units ... until i mentioned getting them from the dealer. unfortunately, i didn't hear that advice until afterwards. that said, others have gone with reman'd halfshafts i believe. i want to say the ones from bmw were around $260/each (and this was for e30 halfshafts, not sure on ti shafts).

Halfshafts from my local STEALER are $328.00 each. I can't afford that.

I tried to type the word (s)tealer instead of dealer but when I submited the reply the word (s)tealer was automatically changed to dealer.
