transmission clutch squeal when engaged

agdetail · May 27, 2014

just installed a new oem clutch, slave, throughout bearings, pilot bearings.

once i had the car back it drives so much better but anytime the car is in gear clutch out it has this squeal. when i press on the clutch to disengage it stops. i thought it was the belt but it sounded like it was from the tranny area.

i did use all the correct tools to remove and install the stuff including the pilot bearing.

any help would be great.

this is on a 05 gen 3 vert.

never had a squeal before the clutch change

also had one hell of a ordeal putting the tranny back in. i had the shaft go into the clutch and then i had to slowly screw all 8 bolts together to push the transmission back.

Check the play at the top of the pedal

The trans should never be pulled into place with the bolts. It should be mated up to the trans by hand firmly in place and the hardware only holding in place. Also it sounds like you may have the clutch on backwards. There is a flywheel side and a pressure plate side, and it must be installed correctly.

I would give Toddy at BBG a call. He is a Viper clutch go to guy.

I doubt the clutch is on backwards as the disc only goes in one way. Flat side towards the flywheel. I did not remove the flywheel. For some reason the shaft did not want to go into the pilot bearing. Everything was perfect centered.

There is a little play at the top of the clutch. I will have to prb bleed it

Also the trany engages much better now and drives a lot better. Is it possible to install it backwards?

you can install backwards, but will not have correct pedal, so no it wont work

i used the pilot bearing install tool to insert it. went on perfectly. hopefully it is not a faulty bearing.

You more than likely damaged the pilot bearing upon installing the transmission due to if the clutch was alighned perfectly with the pilot bearing the transmission should install with a light jiggle all on its own. Pretty much fall into place.

thats what I'm thinking now. hopefully it takes half the time reinstalling a new pilot bearing this time.

I am not an highly experienced mechanic; but, here is what I do to try to make sure things are lined up and not get into problems with getting the trans in easily. I don't just use a plastic clutch alignment tool. Too much slop for my liking. I don't have a steel one that is probably tighter tolerance (next tool to on the must buy list.) In addition to the alignment tool, I use a machinist's 6 inch ruler at the edge of the flywheel to measure how far in the clutch disc is around the circumference, in order to get it exactly centered. (Granted, the center of the clutch drive spines could be off center from the circumference; but, with the alignment tool and measuring, I feel I have the best chance at the input shaft being aligned with both the clutch and the pilot bearing.)

I also use two studs screwed into the flange that I am mating the trans to in order to help guide the trans into place and help judge that the gap on all sides is equal while mating the trans.

Of course, if one has a lift and a nice trans jack, and a friend, it would be a whole lot easier.

well the shaft is tapered along with the pilot bearing so it should slide in with some grease which i used. as for the centering tool, there is a lot of play with the luk but what i did is tighten pressure plate to hold the clutch plate but be able to slide it around. moved it around till the alignment went in and out without hesitation.

i did use the pilot bearing from the luk kit. maybe it was machined wrong.

anyways i will be picking up a new bearing from dodge this week. the car hooks up and drives normally with no hesitation or vibration. is it still ok to drive or will i mess up the input shaft?

I would park it till its fixed- too exspensive to take a chance on messing something up

So if it was the pilot bearing it would make noise while the clutch was depressed and trans in gear. This stops the input shaft from spinning and in turn has the pilot bearing spinning on the input shaft. When the clutch in engauged the input spins at the same speed as the crank so the pilot bearing does nothing. With that if you have to force the trans in with the bolts you could have damaged the bearing or the slave cylinder. I have seen many slave cylinders broken during installations. there is very little room between the input shaft and the inside bore of the slave cylinder. I would pull the trans and remove the slave and inspect the inside bore and look at the input shaft for marks where the shaft goes thru the slave metal transfer. This could account for your noise as the shaft spins while the clutch in engauged and stops when dissengauged.
