02 ZX3 Grinding Noise while in gear
 
[dunno]Background: 02 ZX3 with 89k have replaced in the past year the following: Rear brakes, ebrake cable, idler pulley, serp belt, plugs, wires, complete tune up, water pump, timing belt, all three motor mounts, clutch slave cylinder ( the one under the dash), 3 complete clutches put in the past 6 months. Frist one lasted a week was bad set from O Riley’s. Plate just came apart at rivets, so unrelated.
Second one master cylinder started to leak (made a grinding noise shortly before it crapped the bed) and lost pedal (3 months about 6k), this was the replacement that O Riley’s gave me for the first one. So I hauled to a transmission shop and they put in a Ford OEM set works great now.

I have started to get a circular grinding sound ( almost like a caliper dragging on the rotor) when the car is in gear and not under power. You can give it gas and it does not make it. Take the car out of gear and it does not make it. It is very noticeable 3rd gear 35 to 40 mph. If i rev it past 4k and shift gears it will grind till I reengage the transmission. I started making the sound this morning when it was cold every time i put the clutch in, once it warmed up it only did it in gear.
Car does not vibrate, pull when you brake, the wheels dont have play in them (bad wheel bearing), knock when you turn or go over bumbs.

I had the wife take it back to the transmission shop and they told her nothing was wrong, I may have to take it myself and talk to these guys.

Is this transmission, wheel bearing, axle related? At my wits end with this thing. Suggestions?

Bad synchros, particularly for third gear, are common on these. That would suck, especially given your clutch nightmare. It would mean dropping the tranny again and either rebuilding or replacing. Btw, the clutch master is the one under the pedal, and the slave is the one inside the transmission housing.

Not entirely sure of your description, though--doesn't make the noise under power but worst in 3rd from 35-40mph?

This is an odd one... The description doesn't sound like a synchro issue to me...

True, but hard to tell from the symptoms described. Couldn't imagine what else could be causing it though, unless the shop put in the wrong clutch, so it seemed like a potential candidate.

Carrier bearing maybe? If I had that I would check the front hub nut torque on both sides and tighten if needed and listen for a slight change (when it's loudest, change in pitch, etc..) Just a thought. I've seen brake pads be put on a little weird, and retainer pieces popping loose and making noises.

The noise is on decleration or costing while in gear. Diffently coming from the tranny. Gears could be backlashing on decelartion. Either way tranny has to come out again and guts rebuilt. Just think it may be easier to pick up a rebuilt one than tear mine open to find a bad gear or shaft in addtion to bearings and what not.

Thanks

Anyone got a line on a source for rebuilt trannys?

Anyone?

Anyone know a good source for a rebuilt tranny?

Use your local parts locator, check craigslist, and here on the forums! I just swapped mine with a used one I bought off of Mikeb on here! He happened to live here inmy town, and delivered it to me. You may find a great guy on this site that'll have one near you!

Update: Tore the tranny a part everything looks good, but this thing has plastic cone bearings? Anyway you cant pre-load these or set crush on them ( which is what sets your backlash) so I am upgradeding them to metal.

Did the bearing change solve your issue? I'm seeing the same issue, but mine comes with vibration.
