Body molding (repair N/A or T)

I replaced some molding strips on my car becaue they fell off when I was driving down the street, and some of them looked bad. To remove:
Front - Remove the screw securing the sidelight / indicator assembly and carefully pull forwards to gain access to the plastic clip, which holds the front end of the trim, and pry it out. Remove the rear screw and carefully pry the trim off. The side repeater light then just unclips.
Rear - Remove ( pry ) the plastic clip out and carefully pry the trim off.
Door - Open the door fully and locate the nut at the front next to the door check strap. If you are lucky, the nut will undo, but if like mine it does not, then starting at the rear of the door, pry the trim off until you get to the front, then try sliding the trim off the stud, or as a last resort, carefully pry the trim away from the stud. If the plastic retaining clip comes away from the trim, it can be stuck back on with polyurethane sealer.
Rear wing trims -Front - Remove ( pry ) the plastic clip out and carefully pry the trim off.
Rear - Remove the front screw. It will be easier at this stage to remove the rear interior side trim panels. This allows easy access to the three captive 8mm nuts. Undo these, then carefully pry the trim off. If any of the captive nuts / studs spin, the trim can be carefully forced sideways away from the studs.
Rear end trim - To remove the license plate unit and trim, the tail lights first need to be removed ( six 8mm nuts each ), then undo the two 8mm nuts holding the unit. At the top of the unit, in the center, there is a plastic clip, which I found was best unclipped by using a shock force on the back of it, using some kind of drift ( use a screwdriver if your careful ). When the unit is loose, several wires need to be disconnected, unclipped, and fed through the rear panel.

Now would be a good time to replace the 10+ year old clips, especially if any are cracked or broken.

The Symptoms

When they look ugly, some of the peices are missing, have to remove them to get at some rust, or when your painting the car.

The Difficulty

I would give this 1 star. It is very easy to do, and does not take much time. The only difficulty is paying for the new trim, which is around CND$1500 for all of it. Look in local junk/scrap yards for a MKIII with useable trim, or call Jeff Watson at Jay Marks Toyota.

The Problems

The peices go on great, but while they are off, make sure to clean out any dirt or rust, otherwise you will just have to do the whole process over again.

The Results

It looks great now, no more faded cracked moldings.

Time and cost

Total cost for all of the trim is around CDN$1500, but I only did a door and near the wing. The wing section was around CDN$150, while the door trim was CDN$250. It took me about 30 minutes to complete.

Rear Spoiler leak (Repair, all models)

This is a common problem for the MKIII. If you ever wonder why you get water dripping from the hatch while it's open, it is most likely a leaking spoiler. It is very simple to fix. First, take the cover off the top of the hatch, it is held on by several clips, and 2 bolts for the cargo cover attachment points. Remove the bolts, then slowly pull until the clips pop out. Once you have it off, you will see the bolts holding the spoiler on. Remove the bolts one by one, and remove the spoiler. Thoroughly clean where the spoiler attaches to the hatch. Simply use bathroom or automotive caulking/silicone sealer (Mono brand for example) around the holes and on the bolts.

The Symptoms

Water dripping when the hatch is open, water in the spare tire well, etc.

The Difficulty

Very simple, shouldnt take more than 30 minutes.

The Problems

You might discover rust underneath the cover around where the spoiler attaches. It is best to repair this as soon as possible, as it will only get worse over time.

Time and cost

The cost of silicone sealer, and about 30 minutes.

Loose Door Hinge (Repair, all models)

I had a bad door hinge on my drivers side, so I had to pick the door up or just slam it to get it to close, which is very bad for the door and the car. If you buy direct from your local Toyota dealer, they will only come in black, so you will have to paint them to match your cars colour. This is not a hard repair to complete, it is just a pain in the ass to do. You can't get at the hinges unless you remove the front fender, so to remove the fender, you need to raise your headlights, remove the headlight assembly, and then you can reach your arm in to remove 3 nuts that are holding the fender to the front upper nose peice. Once those are removed, pop the hood and remove the bolts down the top of the fender. Finally, remove the black plastic mud gaurd (its alot easier if you just remove the wheel), and remove all of the bolts that attach the fender to the body. Next, remove the side marker trim, and the front turn signal (one screw on the side near the bulb, and another through the front grill). If you removed all the bolts/nuts, the fender should come right off. If not, check for ones you could have missed.

When putting on the door hinges, have a freind hold the door, or secure it on jack stands, or a similar support. Remove and replace one hinge at a time. When you have replaced both, and everything is tight, make sure the door closes straight. If it does, reassemble your car, and enjoy a working door!

The symptoms

The door is hard to close, you need to lift the door to get it to latch, or there is a large amount of play.

The Difficuly

Its alot easier if you read this tech tip, or you would have had to do what I did, and search around for every bolt keeping the fender on.

The Problems

Be wary of old nuts/bolts, I snapped 2 bolts that were holding the nose peice, and the lower fender. Use penetrating oil (WD40) to all the nuts/bolts before you attempt to remove them, it will make it much easier.

The Results

I am very happy with this fix, now I can close my door without lifting or making alot of noise.

Time and Cost

Well the first time will always take the longest, but it took me 3 hours to do, but this tech tip should help you complete it in roughly one hour, depending on how much diffuclty you have finding/removing the nuts and bolts.

Paint Chips and Scuffs

My car had several scuffs and chips in the paint, so I decided to remove them. We are blessed with not having clearcoated paint. For fixing scuffs, buy a green light coarse pad, the kind you use to wash wishs with. Soak it in some water with a quality car soap, and lightly brush over the scuff until its gone. Grab some polish and with some elbow grease, the paint scuff is gone. T get rid of paint chips, buy some touchup paint (best source will probably be your local Toyota dealer), and one peice of 1000 grit sandpaper, and one peice of 1500 grit. If there is rust, you need to sand the spot down until you hit bare metal. Then use the touch up paint, lightly cover it. Using the 1500 grit, lightly sand away any big bumps. Finally, use the same green pad to finish it up, then polish the spot. However, you cant just polish one spot, you'll need to do the entire car.

The symptoms

If you can see chips and scuffs on your car, then you have chips and scuffs on our car.

The Difficulty

Very easy. Practice on a small spot out of plain view (bottom of from bumper for example).

The Problems

None at all, besides someone cutting me off when i went to the store to get some polish....

The Results

Looks like new paint, it wowed me on how nice my car looked after it was done.

Time and Cost

It doesnt take that long, I did it while washing my car. I fixed the chips, washed, waxed, and polished my car, which took about 4 hours. As for cost, if you already have a high speed buffer, it will only cost you $20-30 for touchup paint, sandpaper, etc.

Cracked or faded paint on wing or any part of the car (Repair)

The paint on my wing was all cracked to hell, so I needed to fix it. You can repair it two ways, with chemicals, or with sandpaper. I chose sandpaper becuase chemicals are very messy. Just rough up the old paint with 600 grit sandpaper, and spray 2 to 3 coats of paint (most autobody shops can match your paint, and put it into an aerosol can for a small cost). Then use a green pad, scrub until it is smooth, then polish it with a high speed buffer.

The symptoms

Bad looking paint, cracks etc.

The Difficulty

Very easy.

The Problems

Nothing

The Results

Looks like new paint, it wowed me on how nice my car look after it was done.

Time and Cost
