depends if you have lift up reverse. if you do its mtx75 if you don't its ib5

Yes I have lift up reverse , will I only find this box on the cars liste above or do the ford connect and focus share the same ?

 

Does it matter if its a td ?

now im home on the laptop i can see my questions are all over dam iphone lol

recently my escort estate tdi thrust bearing has been rattling around if i start the engine with out pressing the clutch im getting a extra loud constant rattleing noise coming from the box are if i blip the gas pedal or pres the clutch in a tad the noise instantly stops and doesnt return untill i knock the engine of and restart it with out holding the clutch down , its 50/50 doesnt do it all the time maybe 3 out of 10 trys.

the thing is its been stood for 2 years ( which shouldnt make a difference ) but before i stored it away it had a new clutch kit put on so in my opinion its either the thrust bearing or the diffs in the gear box does this make sense ? i can get a video of it doing this & upload it

If the noise is not apparent when pressing the clutch surely that proves it is not the thrust bearing?

 

When the car is in gear and clutch pedal not pressed in, the thrust bearing just sits on the input shaft doing nothing.

The thrust bearing is only under load and spinning when it makes contact with the clutch cover diaphragm spring by pressing in the clutch pedal.

 

There is a slim chance the thrust bearing is not sitting in the operating fork correctly.

Some thrust bearing location tabs are plastic, which could be dislodged or snap off when matting the gearbox to the engine.

 

I had similar issue myself a few years ago, noise apparent all the time unless I pressed in the clutch pedal; everyone said the same, as the noise stops when clutch pedel pressed in, it's the thrust bearing.

 

Eventually noise got worse till unable to select gears, once gearbox out, thrust bearing was ok, I was so confident of its condition and appearance, I refitted it with the new clutch.

 

On stripping the gearbox, I discovered the main/lay shaft front bearing had disintergrated.

 

I believe both types of gearbox can suffer from this issue but the IB5 more so.

That noise is the same noise as from my gearbox before mainshaft bearing went.

 

Yet noise from my gearbox was all the time, only stopped when clutch pedal pressed in.

Noise was apparent even with engine switched off and coasting while in gear or neutral.

 

I believe before the bearing case completely disintegrated, fragments were somehow catching the teeth of one of the gear.

When I stripped the gearbox, one gear had lost half of its teeth, actually on one side, if that makes sense.

 

My gearbox is IB5 on a 1.8.

 

It's claimed front mainshaft bearing is susceptible to failure when covered in region of 80k miles.

Issue is apparent on both types of gearbox, the IB5 more so, although personally I've never heard of it occurring on the MTX75.

This the 2nd gearbox I have put on , what's the chances of 2 of these mtx boxes making the same bad noise ? Out of precaution I put a new clutch kit on just to get a new thrust bearing , so feeling a little peeved , woul you say it's still safe to drive about?

When noise first appeared on my car, I instantly suspected gearbox or diff but with so many suggesting it was the thrust bearing, I was convinced otherwise.

 

I took the gamble until gearbox jammed in gear, stopped dead in its track with one hell of a jolt, luckily, I was only reversing off the drive, who knows what could of occurred at a higher speed.

 

I've experienced Escorts gearbox issues on three occasions, first two on same car, 48k miles, there was no noise and on each occasion the gearbox jammed dead, locking the front wheels, couldnt select or get it out of gear.

 

On first occasion I just replaced gearbox, when same issue occurred again within 12 months, after some digging, I discovered there was some kind of design fault with the gearbox housing, which was rectified by strengthening on Escorts manufacturered after 1996, so I replaced with a gearbox from a later Escort, that gearbox lasted another 4 years without issues, eventually I sold that car.

 

More recently, a couple of years ago same issue occurred with another Escort with 78k on the clock, on this occasion I stripped the gearbox in an attempt to fix it but there's was too much damage.

 

On each occasion the gearbox in question was the IB5.

I spoke to a machanic tonight who used to work for ford he said its the thrust bearing just rattling around , he also said it highly unlikely for it to be sat incorrectly but just rattling , I'm still unsure if another gear box will solve the issue or if its just a case of replacing the thrust bearing which can only be bought with a clutch kit, but what's the odds that both boxes were making the same noise ? The previous box kept jumping out of 2nd & 3rd gear that was the reason for changing.

I really appreciate your replys you seem to know what your talking about you've also made me feel uneasy about driving it incase like you say it locks up!
