1998 Oldsmobile Aurora 4.0 engine mount has been discontinued. I’ve looked everywhere I can think no one carries it anymore. Does anybody have A good upgrade or modified mount ideas?
They don't make the torque axis mount for the passenger side of the engine anymore. You can buy the two trans mounts front and rear (or as they are described in relation to the engine's position left and right). On the left you can get an insert. I had to purchase the whole mount for the right side. The rear one (driver's side of car) is hydraulic and available on Rock auto.
The '99 is the only different classic. Instead of having a front trans mount it got the upgraded front motor mount and a different rear insert. The replacement mounts for 95-98 are listed here in this quoted post.
You can buy the whole 'rear' transmission mount including the cast portion aftermarket and from the dealer last time I checked. Otherwise you can just replace the insert. The insert is available at local parts stores and rockauto.
The 'driver side' hydraulic mount is probably not bad but I don't know if it available or not. Probably somewhere. However, mine is good and did not worry about it. I have replaced all of these at once and I can tell you without a doubt it makes a world of difference. If they fail again I will make some polyurethane inserts. HTH.
P.S. Anyone else reading this.... your mounts are likely shot if you have over 100k or there about! Not to mention old compound.
This is Sall's procedure to replace the torque axis mount that involves some welding.
I have also seen these pop up on ebay (someone does the procedure and then sells the completed mount on ebay). Up to you if you want to trust someone else's welds.
This thread goes over the procedure for the front and rear tranny mounts (left and right)
