Rust Under Rear Seat


TR

Recommended Posts

A quick question for any rust experts.  I pulled out by rear seat and as the photos show there are clear signs of rust in the area near where the subframe mounts to the body of my 1973 tii.

 

I searched the forum and did not see any reference to this area but I'm guessing someone has seen this before.  Is this a "known rust problem area" and what's involved with the correct fix. 

 

Thanks!

First thing to do is to scrape the sound deadening off the sheet metal and see what's underneath.  It may just be some very small holes...or it could be worse.  The normal rust spots back there are where the reinforcements that are welded to the underside of the floorpan end, there under the back seat.  You'll need to look under the car, find those reinforcements and then check the floor inside to see if there's rust in those two spots.  After you get the sound deadening up, post some pictures so we can see what lurks underneath.

Mike,

 

Thanks.  I wanted to get some input before "digging into it" only to then find out I should have posted here first and done it the right way.  I'll work on it later this weekend and post pics.

as mike said, do a little more probing to see extent.  this is a know rust area.  unfortunately it is in a complicated and structural part of the car where the subframe attaches.  here is a pic of worst case....73tii...subframe was torn off car due to rust disintegrating where it attached.

Marshall - I'm hoping to not end up there.  :-)

 

Here are my pics.  It seems clear the moisture/rust came from the outside of the car.  I knew the small signs of rust on the inside were just the tip of the iceberg and I'm praying it's not a major iceberg.

 

I think the place(s) I really need to examine will require removal of the rear suspension (which has to come off anyway to get assessed, cleaned and painted.  But I did not know there was another "rust generator" in this area of the car.  Note: the shock towers look perfect so I thought if there was no sign of rust there everything would be fine/minimal.  Hopefully this won't be too bad...

Hopefully I can resurrect this thread...my car (1976 non-tii) is in the worse condition in that exact spot. Broke free on the left side and not too much better on the right....finally got it's place in the welding line and it turns out I have the wrong repair sheets (got the rear floor pans which are pretty much forward of the back seat - makes sense in retrospect) Is there a repair piece for this area? My welder said he could make the neccessary repair but it's a lot less labor $$ if I have the "official" piece. Thanks...
