I've got a pile of driveline vibrations. Rear U-joint was loose so was packed with grease again, I think it just needs replacing. After it was greased a rattle showed up in the transfer case so that's on my junkyard shopping list for the spring. If I hit the clutch hard (press down) I get a bit of a thud. I'm not sure if this is transfer case related or not. It's a bit quieter so I'm not totally certain where it's coming from.

In the last couple of days, I've been getting a faint knocking at lower speeds, both accelerating and braking. It sounds like every few inches of rotation of the tires there's a bit of a knock/rattle/thud from what I think is the rear left wheel. It reminds me of a muted version of a stick or playing card jammed into a bike's spokes.

Am I on the right track thinking that this is the bearings on the rear left? Is replacing these a major job? If I had a few days, some warm weather, and the right tools I'd try to do this but if it is bearings I'm looking at getting it into the shop as soon as possible.

Thanks

edit: oops forgot this bit: ~318,000KM, C8.25 rear, stock all around.

 

ADDCO makes one..

7/8" diameter, which I think, is the same as stock.. but stronger.. unless stock is just 3/4".. I'm not certain. But, I know it's stronger.

 

Okay so after reading even more and paying close attention on the drive home with what I read in mind, I'm thinking that it's just the U-joint getting crappy again. Say I'm rolling at 60 KM/H on flat terrain in 5th gear, when I let the clutch in or out quickly I hear a clunk. I'll test when I go out again in an hour but when I pulled into my driveway just a minute ago the noise didn't happen

 

Anyone have links to an XJ with a four link rear suspension?

 

My rad neck stripped, the cap goes on ok, but the pull up on it a bit and the cap pops off on one side. Has this happened to anybody else? Id like to know what someone did to fix it, other than replacing the whole rad.

Just trying to save myself some money, as im going to school and dont have a job right now, so money is tight.

Thanks.

 

Fixing that would be pretty difficult I would believe, since there is so much pressure there.

 

I have my 99 Sport with 4.5" lift. I have a chance to by some 16" Rubicon Wheels with some almost new 32" tires. Friend has had them in storage since 2006.

I know I will need some of the adapters. The wheels are really deep on the backside. With the Spacer/Adapter, will these fit okay on my stock axles?

RSWiser.

 

Yup. They will fit just fine.... Like they were meant to be there in the first place!

 

Hey, thanks for the info! I'll pass it along to him.

 

Yeah, thought so, i guess ill just have to get a new rad.

Guess ill be hitching a ride with the rents to class now, i dont want to lose anymore coolant and potentially **** something over.

 

Good luck though.

 

I drove without coolant for I don't know how long, bone dry. I probably did **** something over, though, so don't be like me. Just a testament to the strength of our engines.

 

Sounds like your girl is ready for some just plain ole' TLC. 4 bolts pull the drive-line, couple U-joints $10-$20 each (here). If one looks good, save it for a rainy day. Lot's of shops offer free brake inspections. Fluids. Then with all that square you can focus on what's left. Just my $.02

 

Which nipple on heater core goes to tstat housing, which one to water pump, and is one of those lines supposed to be 3/4"? I am eliminating htr core valve and the po ran 5/8" hose on both. Think one is supposed to be 3/4"? Just need to know whick nipple goes to what and which one is supposed(?) to be 3/4"?

 

I've spent most of this month out of the state for work, with the Jeep sitting for around 5 days at a time til I get back. After my second trip out, I got in the Jeep and drove it home normally. The next morning, I heard what sounded like very rapid ticking when I turned (and held) the key. It didn't just click once and die like I experienced before with a bad ground. It then happened again about an hour later while running errands. It was fine for two days after that, but it did it again last night after returning from another trip, and I expect it will do it when I go out there today.
For the three times it has happened so far, my fix has been to turn the heat completely off. After doing this, it has started normally, and the heat still works once it's running. I can't tell where the noise is coming from since I'm in the driver's seat.

Input?
