Not lowered correctly


Recommended Posts

I purchased KYB gas struts front and rear and eibach springs from the z store. I'm bothered by the fact that they didn't bother to mention to me that these struts say not to use with lowering springs. But anyway, I had the parts installed at a local suspension shop and now the front is about an inch higher than stock and the rear dropped a little more than 3 inches no kidding. Can someone help me? Were they installed wrong? The nose of my car points up and my rear tires are now tucked in the rear fenders about 1.5 inches in.

 

I would greatly appreciate any info I can get, thanks.

My thought exactly. The front and rear springs need to be swapped. When I removed my stock springs there was a noticeable difference between the front and rear. My new Tokico lowering springs were marked "front" and "rear". They too were noticeably different.

Thanks, I will look at the the springs for the numbers. I have never taken my cars to a shop other than for suspension work. I actually like the shop I go to, I've had other cars lowered there before. The owner is a great guy and they do good work, but since the owner is getting older now and he has this new guy working there that was the one that worked on the car. I appreciate the input. So the eibach springs are labeled 1 for the front and 2 the rears? I will take a look and definitely take the car back.

 

Thanks everyone.

I took a look at the springs, the rears were hard to take a look at, had to jack the car up quite a bit to get the spring to decompress, but sure enough, the rears ended with .001 and the front part numbers ended with .002. I took the car back this morning, the owner apologized and everything was good, they are going to try to finish it up today. Unfortunately the guy that worked on my car was let go, there were too many complaints apparently on his work.

Thanks again for all the help. I just picked up the car and it looks and drives great. The shop was really apologetic and everything worked out great. Now I need to figure out why my brakes are so soft. I have a new replacement master cylinder, earls stainless steel brake lines, and the toyota calipers....

The soft brake lines to the calipers and wheel cylinders have to be removed when replacing springs. The system must be bled properly afterwards. Sounds like the shop is at fault again, if the car came in with good brakes and left with spongy ones.

If it's not a bad bleed that caused the spongy brakes, it could be worn out soft lines, incorrectly adjusted brake booster, etc. I'd vote it's a bad bleed as leon suggests. While it is possible to change the springs without removing brake lines, most shops will just remove them because it takes less time that way.

I'll have to see about bleeding them again, they were this way before I took the car in. I'll do that and if that doesn't work then I'll do some researching. Thanks again!

Your shop sucks and can't be counted on. Do it yourself. This isn't going to be some new problem or a faulty brake component. They probably had to disconnect your brake lines to get the suspension to drop down enough to compress and change the springs, so now you have air in them. If your brake pedal will pump up some, it is air, nothing else. If it won't, and you still have stock rear drums, you could possibly need to just adjust the shoes out with your e-brake handle. If you have done any conversion of your disc brakes, front or rear, the aftermarket bleed screws are often not truly located at the optimum location to get all the air out of the calipers. I would try adjustint the rear drumbs with the handbrake, and if that doesn't do it, then you need to bleed the master cylinder, then remove each caliper and bleed it carefully while holding it in your hand (watch the fingers) and rotating it around to different angles. Almost every non-stock disc brake conversion seems to have trouble with this.

While learning to do this all by yourself is fantastic, and highly recommended by me (it's acctually a lot easier than you think, your biggest enemy is your own brain telling you you're over your head and making you freak out), it sounds like this problem is not from the shop. I would start with a bleed-the right way, as it's the cheapest thing you can do really. From there, it's chasing what exactly is wrong. While replacing parts is fun, it's not the best option if you don't have an overfilled wallet. Often times tuning something will fix the problem.

Earl's stainless lines will help the pedal feel good and firm. I've got Earl's on my truck and my Z. You said you do too, so we don't need to wonder if you have 40 year old soft rubber lines.

 

Bleed the brakes and make sure there's no air in the system.

 

For the self-adjuster to keep the shoes adjusted you need to set the brake every time you park. Trying to use the E-Brake to take up a lot of slack takes to long if they're badly out of adjustment.

If you've still got rear drums, take the wheels off and check the shoe adjustment. Tighten them up till they just barely rub when you turn the drum by hand.

 

If these two suggestions don't help, let us know and we'll move on to other possibilities.

Rebekahsz,

 

The shop I take my cars has been really good, they had one guy that was new, they let him go and acknowledged their mistakes. If you would've read everything, I said my brakes were soft before I took the car in, and they were no different after they worked on the car. Keep those comments to yourself, that is a shop I can count on with a honest owner.
