Default Front end vibration when accelerating

I thought i've done with repairs,but i was wrong.
On this week i replaced strut mounts control arms tie rods and ends,did alignment,but have vibration during acceleration the whole front end of the car is shaking not a lot but it's annoying.
Took it to the shop they think that's the inner driver or its bushing in the differential,thesaabsite.com FAQ says the same thing.
Have anybody experienced this issue with their cars?

I am currently fighting the same thing. I am pretty sure now it is the driver's side shaft; while I have the car up last night I wiggled the axle and there was about 1/4 inch of play in it.

Not really, but when the wheel balance was "way off" it was just a proper balance job at Reesers of York Haven..
But, if the axle support bearings are worn, then this will have to be fixed. I have read where there is a process for renewing the bearing without removing the transmission......(maybe this applies to one side ??) - but only at the best indy shop or dealer...
Good luck

Inner driver failure is fairly common, if this is the case your cheapest solution is to buy a complete remanufactured driveshaft that includes the innder driver cup.

what about transmission inner bushing ,do i have to replace it as well,what do you think?
Replacing driveshaft doesn't seem like a big deal moneywise.

A vibrating inner driver may cause the diff bearing to go as well, primarily if its the drivers side.

I got a reman complete driveshaft from Napa a while back for $62+85 core, but recent posts on here suggest that nowhere has them in stock anymore. If one cant be found, the inner driver cup alone is $400ish+ to buy new.

what about the inner driver kits they sell through saabsite.com are they worth it? I replaced my intermediate bearing (carrier bearing) on the passenger side today, it helped but I still have a wobble/vibration on acceleration and am thinking I need to replace the entire passenger side inner driver/tripod bearing assembly.

I had this problem and it was both an inner driver and diff bearing.


best best is used driveshaft. Tom's Foriegn Auto Parts it the place to go. Diff bushing is ~25 from a dealer.

The saabsite inner driver kits would be fine...if you feel like dropping the couple hundo on it..I wasn't willing to pay that much.
