Two Problems I hope you guys can Help me with!!

[frontierguy25]

I have a new job where I have to drive a lot in one day, and right now the Supra is my only car.

First, I was driving yesterday and about the 100 mile mark when I got to my first store, I noticed that my over flow tank had spewed out a bunch of brown coolant everywhere like it had over heated or something. I have never had this happen before or had my Coolant look like that. Tomorrow or later today I should say I'm going to do a complete Coolant flush. Anybody know what would cause that? I have a Koyo Race Radiator, and new coolant lines, weird!

Second, I noticed that when I would take a left turn, it sounds like my front passenger wheel is grinding or hitting something kinda like a thumping sound. You can't really feel it in the steering wheel, but you sure can hear it. But it is only when I turn left. I don't know if it is a wheel bearing or it's the fact that my shock is blown on that side. (I'm getting some Bilstein's this week hopefully). It almost seems like it's hitting the bumpstop repeatedly. But the power steering rack doesn't lose any fluid either and seems to be in good shape. I did notice with this that the rotor and brakes are pretty much gone on that wheel as well. It's always dirtier than the rest, I think that is because of the blown shock though.

Any help would be greatly appreciated. I just don't want to go and buy some parts that I don't need to right now and buy the parts I do need.

Thanks in Advance!:icon_razz

coolant issues - new thermostat and radiator cap?
do a flush though... shouldnt be BROWN....
and make sure you dont have any loose coolant pipes or leaks.

 

[frontierguy25]

I've had my Koyo now for about 2 years with the same radiator cap and 160 degree thermostat. Never had a problem with it before. I did just go on a 364 mile trip and had no issues what so ever last week.

If your coolant has been red or light green depending on what you use, and it is now brown and spewing out, especially if you havent overfilled the overflow, you might want to get a block tester for BHG. Brown is not good, especially if its milky consistency.

AFA the suspension, you might want to check your ball joints for looseness/excessive wear. Check the TSRM for specs.

It almost seems like something is rusting, It's not milky at all I've had a BHG before on another stock car bought it that way. I have a HKS HG with arps, hopefully it's fine. I'm flushing it right now.

I'm going to be doing my front brakes tomorrow, and taking off the wheel. It's weird because when driving it today it didn't make that noise. Some body told me that it could be a dragging caliper?? Anyone know what that means?

Thanks Again for the help

means your caliper is seized or sticking-always applying brake force, it would be damn hot and car would prolly pull to the side thats sticking. try spinning the wheel when its jacked, but after driving you will feel the heat.

My car does pull to the right as well. I did jack the car up and I put my hands at the 12 and 6 position and there is no in and out play. But when I put my hands at 9 and 6 the entire wheel moves a little side to side, almost feels like it's going to come off like you were changing a tire.

well the 12-6 ,means your wheel bearing is good, as for the 9-6 -i dont wanna throw anything out there cause i haven't looked at how these cars are setup for suspension/steering

hows your tire wear and is the right side the one with the brakes worn out?

I have pretty new tires on it, probably only 4k miles and the wear so far seems to be even, I also checked the right rear wheel and the wear is even and I don't have any problems with that wheel.

When I push down on the car that is the wheel that goes down the most compared to the rest. But if the wheel bearing seems to be ok, then what the heck could it be??

The only other thing that I could think of is maybe a lower ball joint, or a messed up rack??

Hey Dumbo, thanks for the replies and help it is greatly appreciated.

If you're going to tear into it, it's pretty easy to diagnose once the wheel and the brakes are off.

Might have to get a jack under the lower control arm, but you can move stuff around to find what it is...

 

[lewis15498]

Check tie rods and ends, the steering rack itself and the steering rack mounts
and i would say you have a siezed caliper

I'll be doing this tomorrow, you should come over and check it out. I live not to far from you.

 

[frontierguy25]

How will I know if it is a stuck caliper? will it not compress?

Thanks

 

[black89t]

sounds like your control arm bushing could be replaced.

thats my guess.

 

[frontierguy25]

OK, figured out part of the problem, I took the wheel off and could move the entire assembly, I looked down and my lower ball joints are shot. But will it cause it to make a clunk sound when turning sometimes?

Question: why are you pushing on the wheel in the 9-6 oclock position, or do you mean 9-3... If you have play from the 9-3 oclock position its usually and indication something is wrong with the steering system (play in tie rods, rack, loose rack mounts etc). Worn parts can make all kinds of clunks. All those parts work together when driving and turning, so if one thing is off it can make noise. For the caliper, jump in the car when the front wheels are raised off the ground, push the brake pedal down hard, let go, jump out and spin the wheels, if one side is dragging you know something isnt right there. It could be seized slider pins or it could be a seized piston, but most likely something is wrong with the pins because a seized piston would cause almost no brake power going to that wheel at all.

Yeah I meant the 9-3 positions. I noticed that my Lower ball joints are out, I'm going to check the rest tomorrow, because I had to put it back together to pick up my son from school.

what are the slider pins? Are they at the top of the caliper where I guess they slide on to the assembly? Is there supposed to be a pin that hold it in place or something?

 

[Poodles]

Yep, usually the top pin is the one that siezes. The lower one is floating and is held in place with the bolt.

Is this something that I can replace or do I have to replace the entire Caliper?

Another thing for your clunking sound ( since you said your suspension is messed up ) you may want to look at your strut plates on the front. There are bearings up there that allow the struts to turn with the springs. If those go out, you could be hearing that clunking around. with your tire off, grab your spring and pull and push on it and see if its loose at all. If it is pull the whole assembly and check the top plate.
