All OEM related XJ specific tech. Examples, no start, general maintenance or anything that's stock.
So to today I replaced my motor mounts and my trany mount. They were kinda bad When I was done I took it for a test drive and I feel more vibrations than before. Is that normal? Thanks for your help! I have a 99 Jeep Cherokee with about 270 miles.
Well the clear movement the engine had with no mount may have concealed steering link issues. Start trying to rattle your steering items (tack bar, tie rod, pitman arm, etc) see if anything is loose. I know a guy that though he had driveline vibes but it was actually his track bar bushings that were jacked up. If all that is fine check the drive line.
Well, now that you don't have a 500# engine banging around like a BB in a bucket, I bet you do feel more vibs.
Ever consider doing some basic maintenance and noggin pokin to this poor ole rig? 270k it's about time.
Thank you for the great info! This guy has been through a lot! The past owner made sure of that. Since buying last year I have done a lot of work.About two weeks ago I replaced the wheel bearings that were roaring! Also the transmission, exhaust manifold, steering stabilizer and the list goes on. So don't worry I'm not about to let go anytime soon. I haven't done much suspension work yet. How much of a hassle are they to replace? I'm limited in the tools I have. Not saying I'm not up for the challenge I just want to know what I'm getting into.
Depending on which component it can be very irritating. Even then it can be a shot in the dark. Rust, threadlock, and unknown PO fixes can make for problems and broken bolts. Welding is a good trait to have I've noticed after reading on here awhile.
When I replace the engine mounts, I leave the through bolts and mounting studs/bolts a bit loose. I then start the engine and rev it a few times and shift the auto trans through the gears and back into Park. I then shut the engine off and tighten the bolts. Kinda lets everything "settle in".
Also, be sure to do some noggin pokin where the exhaust goes ofver the crossmember peer the attached photo which I stole from someone here.
Do you get vibrations only when driving or do you feel vibrations in the steering wheel when sitting still?
If while driving, inspect the front drive shaft U-Joints and rear drive shaft U-Joints for any evidence of wear.
Is your Heep lifted?

Ok so checking things out a little more, so the jeep is lifted 3" the exhaust hanger piece that is supposed to hold up the exhaust is broken and needs to be re welded. I feel the most vibs when I am in reverse especially but I feel some in idle and in drive sitting still. Do you think there might be something wrong with the transmission? I also have a small ticking noise coming from the bell housing but I think that's just from the screws holding the flex plate to the torch converter rubbing against the out side cover.
Also looking under the jeep and around the suspension I can see bushings that are cracked and sagging, also I still have the stock track bar. Doing some reading and exploring some say that I need an adjustable track bar. Which seems like a good idea. If I replace the control arm bushing's is it easier to just replace the control arms as a whole piece or just the bushing's? Thank you guys again for your help!
