WELL I HAVE 2 AUDI'S...ONE 99' A4 I.8T QUATTRO AND ONE 97' A4 1.8T WITHOUT QUATTRO...I MESSED UP MY AXLES ON MY 99 A4 AND AM WONDERING IF I CAN SWITH THEM UP WITH MY 97 ONE??? PLEASE HELPP ME IF U CAN??

I don't think so. Check out www.ecstuning.com or www.germanautoparts.com and compare part numbers for quattro vs non-quattro axles. I'm pretty sure they're not interchangeable.

um... no. not only are 97 and 99 somewhat different, but quattro and non quattro are very different. some miscelanious parts may fit but for the most part no.

especialy if you are trying to take the axels from a 2 wheel drive car and put them on a car with 4 wheel drive. they will fit just as well as the axels off a ford F150.

yeah +1 that they won't fit. and relax with the caps man... take it easy
