do you have to drop the diff to reach it and what do you think a shop would charge to do this.

 

The rear end has to be dropped to remove the tank.

 

IF YOU ARE REMOVING THE TANK TO REPLACE THE PUMP IT IS EASIER TO CUT AN ACCESS DOOR UNDER THE REAR HATCH CARPET. THATS WHAT I DID EVEN PUT A HINGE ON THE PIECE I CUT OUT FOR EASY FUTURE ACCESS

 

That is what most shops usually do, but leave the hinge out and still charge you for dropping the axle. Some manufacturers had the foretought of building the trap door into the car. Have you had any problems with water spalshing up thrugh the opening?

 

The rear end DOES NOT have to come out. All you have to do is drop the exhaust.







I have done loads of them. The older 86-92's are a little easier IMHO.

This is with a convertible. A non vert will be much easier to and faster to do.

Good luck!

 

I did the trap door on mine. its very easy. i made a plate larger than the hole and used some silicone to seal it, so if i want to open it up later i could peel the plate right back up.
