HITHERE am getting HITHERE really bad vibration aroung 65-70 mph, it seems to be coming from the driveline somewhere. It also seems to get worse when HITHERE take it out of gear and let it coast at that mph. Does anyone know what could be causing this?

thanks

 

tires out of balance...driveshaft (common).u-joint....tranny mount...motor mount....steering components.....I would start with having the tires balanced.

 

Well I took the driveshaft out and had it checked and it was out of balance while the shaft was out I turned the pinion just to check and I could feel the bearing grinding. I have not pulled it apart yet to verify but I hope it is only the bearings.

 

sounds like you found your problem...or problems . ....hopefully there is no damage in the rear..is the gear oil up to level? usually there will be some leakage with the bad bearing......any problems there?

 

well I had to replace the pinion bearings but the gears were ok, I did find out that I have 3.23 gears and not 3.42 gears so I quess I need to change my sig.

 

amazing what you can discover, when you remove the cover!

Wow! I 'm a poet!

Have a great weekend!
