1990 jeep wrangler clutch problem

Home  \  Repairs & Maintenance  \  1990 jeep wrangler clutch problem

my dad just bought a new jeep, and told me that if i fixed his old one, i could have it. it is a 1990 jeep wrangler. all it needs to be driveable is a clutch. i am looking at spending as little money as posible, so i was wondering how much time, trouble, work, ect. it would take to put it in myself.

provided you have some mechanical ability, it shouldnt be that hard - grab a Haynes manual for the jeep, and follow instructions.

As for cost...the clutch kits can range from 150$ to over 200$... depends on the quality, and what's included - most shoudl include the pressure plate, cluth disc, throwout bearing, possibly a pilot bearing, and generally will have an alignment tool.

Might want to check out the flywheel when you've got it cracked open as well...

how much do u think it would cost to have a mechanic do it? i know i cold probably do it, but finding the time to do it would be hard. how long do u think it would take?

A mechanic would probably take 1-2 hours to do it and costing maybe around $400-500. All thats really needed is to drop the tranny, pop it in, and put the tranny back. Without a transmission jack it is hard to do. Of course it ain't as simple as just popping it in either though

ok, with all that said, what would you all suggest me doing? i really would rather not spend more than $500 doing it. what could i use intead of a tranny jack? does anyone know of any good sites that would help me?

Well when I did mine I used a piece of wood on top of a normal floor jack, but you need 2 people to do this. They do have attachments for floor jacks to make it a tranny jack for only about $50 or $60 (type "Transmission Jack" on ebay. I found 2 that are around $50 each with shipping)

List your year, make, model and engine size and I can probably get a list of instructions to help you out. Best bet would be to buy a Haynes manual for your car though as it has good instructions and some pictures in it. If you don't want to buy one of those I have Mitchell's OnDemand so I could give you the instructions just no pictures

well it's a 1990 jeep wrangler 6cyl. i thought my dad had a manual but i cant find it anywhere. he may have just borrowed it from someone tho. so i would appreciate it if you could send that to me. thanks for the help.

also, i talked to him last night, and found out that the tranny syncs were bad. Is there anything i could do besides rebuilding it, or buying a new tranny?

Remove transmission assembly. Place reference marks on clutch cover and flywheel for reassembly reference. Evenly loosen clutch over bolt one or 2 turns at a time until clutch cover spring tension is released. Remove cover bolts, clutch cover, and clutch disc.
Check all components for wear or damage and replace as necessary. Using clutch alignment tool, aligh clutch disc and loosely install clutch cover with reference marks aligned with flywheel. Tighten each cover bolt a few turns at a time to specification.

There is also how to change the Hydraulic throw-out bearing, pilot bearing, and clutch master cylinder if you need that too.
