    What fluid for the rear end of an 01 GT?

    Interesting...I am looking in the Manual that came with my car(1999 GT) and it calls for Motorcraft SAE 80W90 Premium Rear Axle Lubricant for both the 7.5 and 8.8 inch axle(only difference is the capacity). I also know another guy with a '99 that runs 80-90 and he knows what he is doing. That...

    GT Sparkplugs

    I let my stock plugs go 90k and after seeing them I would definately have done it at 50k or so. They looked fine, but the electrodes were extremely worn, which made excessively large gaps and led to some pinging. So, I think the 100k spark plug change is pushing it a little unless you drive...

    What fluid for the rear end of an 01 GT?

    I have a '99 with 101k and my manual calls for 80-90 and says it doesn't need to be changed unless its leaking or submerged in water. However, I still want to change it and was wondering if at this point I should stick with the 80-90...assuming that is what Ford actually put in there as it has...

    transmission fluild

    I have a '99 with the T-45. Manual calls for Motorcraft Mercon ATF and I have used it for 101k with no problems. It shifts great when you are getting on it. Some people like the more expensive synthetics because the shift smoother during normal driving. However, I'm going to put what Tremec...

    TRI-AX PROBLEM!

    That is fine, but tighten those 4 bolts down to the tranny...they should not be loose. As long as you are getting in gear and don't have any grinding going on you shouldn't hurt anything. Shouldn't have any metal flakes either whatever that was about. Yes, you are supposed to leave the little...

    TRI-AX PROBLEM!

    Yeah...you sure you got the right one? Seems obvious, but it should be a little stiff...not extremely hard to get in any gear. Doesn't sound right to me.

    I think your wife may be right.

    Dashboard Chirping Noise!

    I have had the chirp(baby birds in my dash) periodically when driving highway...ever since I can remember on my '99. I think it has gotten better if not completely gone away on its own. Don't worry about it...just turn up the music or get a louder exhaust. I wouldn't dare let them try to...

    Squeaky belts

    If you are due for a belt then I would try that first. Get a goodyear gatorbelt. Autozone has them. If that doesn't work it may be your idler or tensioner pulley.

    Mach 460 Problems

    Personally, I would go by a local shop and ask them what harness they use. The local shop here is Go-Ho Auto Audio and they actually installed my new head unit recently and it works fine with the rest of the Mach460. However, I know they had to order a special harness they do not normally...

    warranty for brakes only 18000?

    That is ridiculous. If its not the pads or rotors then they need to fix it under warranty. Besides, you would have to absolutely kill your brakes to wear them in 18k miles, so it is hardly wear related. He is trying to pull "breaks are a wear item" game...that won't fly at ford dealers I go...

    JLT RAI Question?

    This was actually one of my major complaints when I first got my RAI. It was a cheap plastic MAF adapter and clearly was not air tight. At first I put some sensor safe gasket maker on there, but I wasn't happy with that as it was ghetto. So, I found a nice billet aluminum adapter somewhere...

    cooling system question

    Pretty sure the cap itself relieves pressure at a certain point...not sure what that is.

    JLT RAI Question?

    Just make sure the rubber coupler that connects the pipe to your throttle body is as far on the throttle body as possible. I had to actually trim some off of my rubber piece to make it go on further. If everything else is on tight that is going to be your main adjustment and it will pull the...

    Seafoam

    I believe the majority of the white smoke is the Seafoam burning. I saw my friend with a '00 and 45k use it and then right after that watched my friend with a '96 and 150k use it(both for the first time) and they smoked about the same.

    Ping Detonation

    I had pinging because my stock plugs(which go 100k right?) had 90k on them and the gaps were way too big since the electrodes were worn considerably. I have Autolite 764s now which i will change every 15k or so.

    Steeda Underdrive pulley install.

    On my 99, the crankshaft bolt was extremely hard to get off. Had to get my friend with his "gorilla arms" and he used a ~2ft long steel pipe on a ratchet, but it seemed like the car was going to come off the ramps before it broke loose. Then we go to do it on his 2000 and it comes off pretty...

    help with X-pipe...

    As long as they re-used the stock metal gasket on the passenger side you are fine. I reused mine that had 90k on it and it works fine. Unless there is something noticably wrong with it.

    help with X-pipe...

    It is probably fine. The offroad pipe makes alot more noise and you can hear stuff you couldn't before. If you start the car up after its cold you can feel around the joints and probably tell if you have a leak. I even put mine up on ramps and felt around the driver's side where it meets the...

    Dragon Plenum and Stock TB. Worth it?

    I have the Dragon 75mm tb/plenum on my NA 99 will no ill effects. I recommend the combination and believe I have top end gains from the combo. The tb is a very nice piece if you care about that. I do not think it messes up air/fuel as it is not a big enough mod to require a dyno tune. My car...
