It's ready for high school duty.īy the way, the universally hated, $60, lifetime warranty, AutoZone, 'start-rusting-straight-out-of-the-box' axles I installed on this Jetta at around 210k miles are still working great. Good thing my wife's current commuter, a 1995 Jetta with 260K miles (replaced a ton of stuff on it at around 200K including the head gasket) is still running well and leaking no oil whatsoever, although about 2 quarts a month of it is going out the exhaust. So our Passat really is "special." :crazy: Same basic engine as the others, but for some reason the engineers chose to use the smaller hubs with this particular engine code. Application references found for the larger hubs on the 1.8L B5 and B5.5 Passats include engine codes AUG, AWM and BHW. Doable, probably not practical unless my buddy at the wrecking yard will give me a really good deal.
Swapping hubs would, therefore, require swapping the entire spindle to accommodate the correct bearing size. From what I can tell, the 33 spline hub uses the 75mm bearing while the 38 spline hub uses the 82mm bearing.
I need to clarify my original hub-swapping comment. May have to put the failing OEM's back on until we can figure it out. A request has been sent to Marty at Raxles to see what he can do. It would seem that an outer CV joint with the 33 tooth spline would swap with a 38 spline unit if the axle tubes were the same design. :driving:Ĭlick to expand.None locally that I know of. It would be nice to hear from anyone else who might have also run into this situation. There has been little mention of this hybrid, dog eared-flange/33 spline issue in the forums, which tells me our new old B5 must be very special, and not necessarily in a good way. Keep in mind that if hubs are changed, bearings will need to be changed as well since the assemblies must be pressed out and in. The ones listed for the 2.8L are 38 splines. Of the hubs I researched, the ones listed for 1.8L B5 Passats are 33 splines.

So how did this seemingly run-of-the-mill, manual transmission Passat end up with an OEM axle configuration that no one makes aftermarket axles for?īefore someone gives the ubiquitous solution as “Raxles” (yes, I’ve purchased their axles before), I decided to see if changing to 38 spline hubs might be a smarter, long term solution for compatibility's sake, since the rest of the aftermarket, axle-building world seems to think my wife’s Passat is a Frankenstein. The axles I received are the correct OEM lengths for each side respectively, just the wrong spline size.Īxles generally listed for B5 automatics have the dog eared inner flange and 33 tooth spline, like my manual transmission OEM’s, but are a good inch shorter. Every aftermarket axle supplier I found listed the dog eared inner flange axle as having the larger 38 tooth spline, and the non-dog eared inner flange axle as having the smaller 33 tooth spline. My wife’s Passat has the dog eared flange.Īfter the new axles arrived and after removing the worn OEM axles for comparison, I noticed the spline shaft on the new axles was larger. Those familiar with this road know there are two inner axle flange types for the B5 Passat: the serviceable type where the connecting bolts slide through the perimeter of the inner CV housing (seem to be the most common), and the tripod, non-serviceable type that are attached through dog ears at the perimeter of the inner CV flange. My wife didn’t want me to put too much into this commuter so I ordered a set of new, low cost axles from a California parts distributor. Correcting minor problems early keeps you from paying for bigger ones later. It runs great, but with 148k miles, it needs the usual maintenance including an ABS module repair (done) and new axles.Īcceleration and deceleration generate the typical torque shudder or vibration indicative of worn CV joints, although it’s minor. :b5: Having worked extensively on dozens of my own vehicles including numerous Audis and Volkswagens, I have apparently wandered into the Black Forest with the recent purchase of my wife’s 2000 Passat (1.8T, manual transmission).
