Ok so im about ready to pull my trans and switch out my flex plate. I really hope that is really the problem, ive had about 3-4 different shops tell me that is what it is.
Originally thought it was a rod knocking, but then took it to a trans shop and they took off the inspection cover(to see if the torque converter bolts were lose) and they tightened them up for me and it still made the same noise but they said there was some (ok a good bit) slack in the flex plate and they recommended that i replace it.

So back to me about ready to fix it.
1. is there a place i can order a replacement without going thru the dealer ( and yes i have checked the parts warehouses, (advance, oreilys, autozone, napa, ect )
2. this will be the first time i have pulled a trans ( and i do have a trans jack that i can use) but is there anything i need to know before i do it
3. is there anything i should get and replace while i have the plate off the motor
4. any general advice would be great

By the way its a 1998 Jeep Cherokee Sport 4.0 aw4 automatic with the chrysler rear in it. thanks for the help

I've got a Flex Plate (97+) in the garage that I have no use for. $50 shipped.

 

if it is new ill take it if it is slightly used its a maybee

 

It's used.

 

hey can u get a part number for me off of it and a pic would be nice to if possible but def the part#

 

What the hell does "slack in the flexplate" mean??

 

It means absolutely nothing to me. "Slack"? What in the world is "slack"?

 

ok let me explain,
when i took it to the trans shop they showed me that you can turn the plate about 2-6 inches without turning the crank at all and yes it was still connected to the torque converter
but i might have a new problem i am having trouble finding the plate does anyone have a way to look up a vin and tell what parts go on it

if so the vin for my jeep is 1J4FT68S2WL234264 and the part number that i got off line was that it would be one of 2
they are 52117761 or 52118551

i just dont know what the right part is

 

Broken in a nicer way.
I've changed a few. They aways crack around the crank shaft bolts.

 

oh yeah by the way if that is the right part numbers that will fit it anyone got any idea were i can buy one thats not from a dealership they want a small fortune for it
no kidding like $150 for the plate itself no bolts or anything

 

Websters has the word slack in it maybe brush up on english or maybe read a book.lol

 

you can get one from rock auto quadratec and many other places , they were all made by omix even the one from the dealer is omix . i cant remember where i bought mine but it was 84 bucks shipped . type in jeep parts and it will come up with a bunch of places

 

uplndvpr here is the part number you need. took this off of the flexplate i have sitting here waiting to go in. its "52118551" thats the stock number i hope it helps.

 

I've heard the word "slack" all my life.

As well as "shackley", which means essentially the same thing.

 

http://www.jeep4x4center.com/ Part # 52117761 for the flexplate and the price is 80.99 plus shipping but still like 100.00 with shipping so i hope this also helped
