Now on to my current project:
Underbody/Suspension Restoration & Rustproofing
Ok, lol so basically what I'm going to be doing is giving the complete undercarriage of my car a little TLC. I guess you can say I'm a little bit of a perfectionist, I mean I know it's pretty unlikely someone will ever come scope out the underside of my 240 at a car meet or something, but I like to know that what I
do have under there is clean and solid.
Here's just a basic outline of what I plan to do:
-completely degrease undercarriage
-fix bent/rusted pinch weld lip that runs under car, prep for POR-15
-find any rust in wheel wells and underbody, clean and prep for POR-15
-drop entire rear subframe assembly along with all suspension members
-POR-15/Paint rear subrame, respective suspension members, front suspension pieces, gas tank, and rear differential
-completely re-undercoat entire underbody/wheel wells with Dupli-Color Rubberized Undercoating
-new hardware for most suspension pieces and rear subframe
So last weekend I brought the car to my house to fix the bent up pinch weld, and degrease everything. Being that the storage unit I keep my car at doesnt have power, or a water connection for that matter, I have to plan things so that I get done whatever requires those things at the house before I take the car back to my unit for the remainder of the project.
First I got the car completely up on jackstands. Here are the pics of the pinch weld lip thing I was talking about. It was pretty bent up in different areas on both sides of the car, possibly from botched attempts of lifting the car from it in the past maybe?
note the smashed rear passenger frame member...previous owners
I went to town on the lip with a pair of channel lock pliers and a hammer. I was able to bend and straighten out the lip for the most part on both sides, I mean it still didnt look too hot but it's a lot better than it was before. After I got the lip as straight as I could, I took a wire wheel to the areas I fixed to get rid of the rust.
the driver's side up near the fender was pretty mangled up, I did what I could
this thing will be my main tool for the next couple of weeks haha
Well when I was pounding away on the lip, I did a little detective work with the hammer and found small patches of rust in both the driver and passenger side wheel wells. At some point there must have been rust in there and someone sprayed over it with undercoating or something because I didnt know rust was there until I chipped away at it with the hammer. Regardless, it's nothing too crazy, and I've caught it early enough and hope to address it properly, but I'm no body man by any means! lol

Now like I said before I will be doing the POR-15 on any parts of the car that I cant take off, in my storage unit. So I just left the lip and rust areas down to bare metal, because I can do the rest of the prep/paint for the POR-15 from there.
Once I got that taken care of, I started the process of degreasing everything under the car:
simple green, no backyard project is complete without it!
just a little bit of scrubbing and some scraping, and a lot of grime came off the driver's fender well
I didnt really take any other pictures while I was degreasing everything(I'm sure you can imagine what it looked like). haha it was a pretty dirty process, and I didnt feel like getting up and snapping pics while I was sprawled out under there. I will say though, from being under the car, I could tell that at some point somebody sprayed some heavy undercoating on a lot of areas on the undercarriage. I'm not sure what went wrong though, whether they didnt degrease/clean it enough before they shot it, I dunno but for some reason a lot of it never cured right and it turned into a liquid tar/black grease substance and stayed like that. Nevertheless I spent a good deal of time ruining my scrub brush and scraping to get it off where it never cured. Here's a pic of some of what I'm talking about:
goop.
Once I had things all cleaned under there, I buttoned her up and drove back to the bat cave, where I then proceeded to put the car high atop jack stands once more, but this time it's going to be for awhile. The next phase is to drop the whole rear subframe and all related parts. Once I do that I will be able to disassemble things and take them back to my house so I can clean and paint them with POR-15. Obviously while I have all these parts off it will be a prime opportunity to get in there and fix any rust spots and spray the underbody with new undercoating.
Phase 1:
-drop subframe
-disassemble parts, wire wheel, then paint or POR-15 rear suspension components, including rear diff and axles
-drop gas tank, wire wheel, then POR-15
Soo here we go haha
I like this shot of the tires, why not throw it in?
this is what I have to work with...not bad, but could be better
half of the exhaust
Tanabe Racing Super Medallion...probably going to be selling in favor of a Greddy Ti-C setup, if anyone should want it
other half out
someone ganked my exhaust man!
supporting RLCA while I loosten the top shock mount nuts
TEIN Super Street coilover...gets the job done, might upgrade in the future
close up
rear swaybar end link a little crustyyy
rear swaybar bolts out
gas tank splash shield thing out
passenger rear gas tank splash shield out
rear driver's side:
rear passenger's side:
gas tank filler neck
I found me another rust hole woot woot!
close up, not too bad
rear brakes off
disconnected e-brake cables
NICO's fabricator's market at its finest haha
loosening driveshaft to rear diff. bolts, I found it's easier to leave the transmission in gear and then break them loose
maybe one day my car will make enough power to do this without even looseing the bolts haha...drive shaft chillin
peepin' at the diff.
Now first I was just going to use one board to support the rear subframe while I was lowering it down like this:
thennn I decided to get fancy and do the whole dual board set up, haha it kind of came back to bit me, you'll see
so I started to do work on the main front 2 bolts of the rear subframe that hold it to the car, hardware and plate
looky what I found! energy suspension subframe bushings, score.
then it was on to the back 2 main bolts for the rear subframe, hardware off
rear bushing
Then it was time to FINALLY lower this badboy. I started to let up on the jack and the subframe was dropping pretty nicely, but as it started to drop more and more, I noticed it was tipping forward a little bit. Hindsight being 20/20, I should have had the jack in a little farther under the assembly, but at that point there was no going back! haha it came down all right, just not exactly what I was going for:
outttt
then dragged it out from under the car and cribbed it up on the wood planks
Here's some pics of the subframe assembly and rear diff. in all its glory:
Here's my handywork at rigging up the rear calipers and driveshaft:
There's a little bit of surface rust above where the subframe sits, no biggy though:
it's so weird seeing it so empty haha
gotta give props to the shop manual, it does help sometimes!
SO, this is how I left her when I finished up this past Wednesday night, and is how the car currently sits. I'm
FINALLY now up to date on where I'm at with the car lol and I hope more people start checking this thread out more, because I kind of feel like I'm talking to myself...let me know what you guys think so far!
PS: It's been awhile since I did all the research on how to identify your rear diff and I don't remember being able to find out anything on a 5 bolt VLSD that you can use on the s13. I will obviously research again if I have to, but if anyone sees this and can identify what car my diff came out of I'd realllly appreciate it, thanks!
