    New owner - spare/rebuild/longevity ?'s

    Hey guys - proud (now that it's running!) new owner of an 89 iX 4 door auto that I picked up for $700 :shock:.

    Almost completely rust free, one small quarter sized spot on the PS fender dogleg, and a small spot on the lower rear corner of the front passenger door itself. No rust in trunk, lower rear valance, rockers, shock towers.

    The car has 267k miles on it, and was previously in Palm Springs, as well as Colorado. Was dealer maintained until at least 210k. Last owner was an 18 year old kid, who loved the car, but didn't have a whole lot of money, nor a lot of knowledge about BMW's. When the stalling problem happened (see other post), he threw a lot of parts at it, albeit Advance Auto/Autozone parts. I've now gone through and replaced the horribly gapped platinum spark plugs, cracked dist. cap, clogged fuel filter and fuel pump, and a few other things are next - t-belt, pump, belts, etc.

    I had another 90 325ix that was hit in the rear, that got stripped out. I still have the front diff, front driveshaft, and a few other odds and ends. Starting with the front diff, I'd like to rebuild/restore, then install and do the same to the parts that are taken off.

    My question - what/how can you fix/restore/repair the front/rear diffs on these cars? How about the t-case? Is it possible? The car has a rear wheel bias right now, even when slipping, but the fronts are getting traction.

    Also - I'd like to do a drain/fill on the diffs and t-case. What's the best fluid to use? I can't imagine it's been done recently.

    Thanks!!!

    you can replace all the seals and bearings on the differentials, same with the transfer case. the bearings may or may not need redone, but seals are always a good idea.

    the thing with differentials is you have to set the pinion depth correctly, which is done with shims. you can attempt this yourself but if you set it wrong the diff will be noisy and wear faster.

    also, the ix is supposed to have a rear wheel bias at all times.

      Any recommendations on who/where to bring it to have them rebuild them? What's the cost of something like that? I'd start with the spare front diff...

      I know the rear wheel bias is all the time (37/63?) But if the rears start slipping, how much will it transfer to the front? In deep heavy snow the rears spun like crazy and the fronts rather slowly (this is from someone outside watching.)

      I've heard of a "jack" test to check the xfer case/front diff or something? How does it work?

        The wheel bias is 67/33.

        Youtube the jack test - you jack up the rear (on a jack with wheels), and put the car in gear.. the front should pull the car forward, and the rear wheels shouldn't spin excessively..... youtube it, you'll get it..

          if the rears or front slip it can transfer 90% of the torque to the other end.

          if it's working, it works very well. I was told at least three times by different people that I wouldn't be able to get in/out of their driveway due to the deep snow/ice (2 feet in some places)... they were all stuck and even the big trucks had a hard time (my brother in-law had to chain up). Made it just fine every time. the amazing thing to me is my xfercase is over 250,000 miles and still working beautifully :o
