Re: 9-3X intermittent shudder while driving at highway speeds Posted by Bernie [Email] (#1501) [Profile/Gallery] (more from Bernie) on Wed, 28 Feb 2024 09:55:33 In Reply to: 9-3X intermittent shudder while driving at highway speeds, GoldenSaab [Profile/Gallery] , Tue, 27 Feb 2024 08:53:12 Members do not see ads below this line. - Help Keep This Site Online - Signup |
Hello,
There could be many reasons for this type of vibration. First a few questions
1. Has the regular fluid mainenance been performed on the AWD system. I think the rear dif fluid is every 40k and the transfer case front dif should be every 60k.
2. Try to pinpoint if the shudder takes place under acceleration, steady cruising etc.,
3. Have the rear axle shafts or drive shaft ever been replaced?
Let us know these answers and we may be able to pinpoint some places to check. Good Luck, Bernie
