CHINOTJ Posted March 11, 2011 Share Posted March 11, 2011 Hi Guys, I am in need of your knowledge again, I have been trying to improve my MJ suspension feeling, make it a little softer, I starded replacing the fallowing components. First thing I did is put a 3/4 of an inche coil spacer on the front in order to level the car because it was a little lower on the fornt when i bought it 8 months ago, then 6 Months ago I replaced the 5 shock absorvers with new ones, one for each tire and the one on the front suspension, and also replaced track bar, 5 months ago I replacede the stock sway bar with a ZJ V8 Sway bar with new bushings, 4 months Ago i bought the links from the sway bar, and installed new ones on wich I have a question. When I removed the old links from my MJ the car the truck lisfted about 1 inch from tire to fender automatically as soon as I loosen up the bolts, is this normal? when I put the new ones I had to sit 3 people on the hood of my car in order to make it go lower and install the new OEM links, did I do it correctly or should i buy 3/4 of an inch longer links to put in to my suspension? i Since yestarday, I noticed that my when i got my truck to speed over 50 M/H, velocity and then put it in neutral gear it started to feel a little shaky on the suspension, would any body have any idea why this would be happening? Is there any thing else i need to change in order to make my suspension feel smoother? Thank you for your help as always. :huh???: Link to comment Share on other sites More sharing options...
NewfieMJ Posted March 11, 2011 Share Posted March 11, 2011 Sounds like your sway bar is holding down the truck . I would recomend extended sway bar links . It should have no effect to ride height . The harsh ride is from the sway bar not allowing the suspension to do it's job Link to comment Share on other sites More sharing options...
Dirteatr717 Posted March 11, 2011 Share Posted March 11, 2011 Look for 2" Lift sway bar links it should help smoothen everything because like Newfie said it's holding the coils down making it a rough ride and the "shock" for the front is called a steering stabilizer :thumbsup: Link to comment Share on other sites More sharing options...
mkbruin Posted March 11, 2011 Share Posted March 11, 2011 You should be able to grab a set of rear sway bar links off a 1980-1997 F350. Should be a bolt-on swap for a longer link. Link to comment Share on other sites More sharing options...
05mxdiesel Posted March 11, 2011 Share Posted March 11, 2011 92+ cherokee links are exactly 1 inch longer than stock comanche links. Worked out perfect with my 3" lift. Link to comment Share on other sites More sharing options...
Pete M Posted March 11, 2011 Share Posted March 11, 2011 what tires? at what pressure? which shocks? Link to comment Share on other sites More sharing options...
ParadiseMJ Posted March 12, 2011 Share Posted March 12, 2011 How are your control arm bushings? I put in new uppers and lowers and my MJ is like a whole new truck. I also replaced the old leaf bushings. My poor XJ is getting neglected now that the truck is sooooo much smoother. Link to comment Share on other sites More sharing options...
tbrand Posted March 12, 2011 Share Posted March 12, 2011 I know that my bushings are pretty tired, and my ride is... jarring, sometimes. How hard of a job is it to replace them? Link to comment Share on other sites More sharing options...
Pete M Posted March 12, 2011 Share Posted March 12, 2011 don't bother. get a set of WJ control arms and get younger bushings AND a much better design (both the bushings and the arms themselves) :thumbsup: Link to comment Share on other sites More sharing options...
CHINOTJ Posted March 12, 2011 Author Share Posted March 12, 2011 Hi Guys, Thanks for our feed back, I really appreciate it, I think I will be getting XJ 92+ sway bar links since they are easier for me to get a hold of. Regarding the tires I am runnng are General grabbers AT2 all terrain, 30X9.5 R15, Tire preasure 38Psi, The Control arm bushings are new I replaced them together with the control arms. Today I noticed that the vibration i am feeling is only in neutral position, if I am going on 4th gear and accelerating I don't get vibration but as soon as stop accelerating and put in neutral position it starts go vibrate, could it be the drive shaft? how can i check if my drive shaft is in good condition? Thank you in advanced. Link to comment Share on other sites More sharing options...
Eagle Posted March 12, 2011 Share Posted March 12, 2011 There is no reason in the world why 3/4" lift spacers, which on an old truck probably barely returned it to stock height, should require 2-inch or even 1-inch longer sway bar links. More likely, the sway bar is rusty and is binding up in the bushings. I would remove the sway bar, clean and sand it smooth where it rides in the bushings, paint it, spray silicone on the bushings, and reinstall.

mnkyboy Posted March 12, 2011 Share Posted March 12, 2011 He said he put in a v8 ZJ sway bar with new bushings 4 months ago. I'm wondering if the ZJ bar is what's making his links too short. Are the ZJ links longer? Link to comment Share on other sites More sharing options...

Are the ZJ links longer? That's another point. I assume the ZJ bar was swapped in because it's larger in diameter. Which bushings did you use? If you used the original MJ bushings with a fatter ZJ sway bar, the bar can't rotate like it's supposed to and that could explain why the suspension feels bumpier.

mnkyboy Posted March 12, 2011 Share Posted March 12, 2011 That is a good point,I would remove the links and see if the sway bar moves you should be able to move the sway bar up and down with little resistance. Link to comment Share on other sites More sharing options...

Sorry if that seems obvious, but suspension work is new to me. Link to comment Share on other sites More sharing options...
mnkyboy Posted March 12, 2011 Share Posted March 12, 2011 No, they will need some minor work to make them fit. There's a few write ups on it. Link to comment Share on other sites More sharing options...
CHINOTJ Posted March 13, 2011 Author Share Posted March 13, 2011 Hi, Today I changed the links on my sway bar, I bought new ons for 92+ cherokee and it feels better and softer. And the bushings i used when I replaced my sway bar were new bushings from a ZJ not from an MJ, so they were the correct ones. And when I put 3/4 of an inch I typed wrong, what I have are 1 3/4" inch. Going back to my drive shaft question how can I check if its in good condition? Thanks.

freakjeep93 Posted March 13, 2011 Share Posted March 13, 2011 to check the u joints justwiggle the shaft and check for movement in the joints. to make sure its straight awtch the saft while its turning and see if its wobbling Link to comment Share on other sites More sharing options...

CHINOTJ Posted March 18, 2012 Author Share Posted March 18, 2012 I have been absent a couple of months but I am getting back in to this. I put the zj sway bar wich is larger diameter but i also made sure to put correct bushings on it, actually I had to go twice to the store the first ones they sold me where for thinner sway bar and they couldnt fit so I had to go and get the correct ones. The shocks I have are stock shocks I don't know part number or size since I just went to replace them at a tire shop, only thing I know is they are duralast. Tires are 30x9.5 r15 General grabbers, with around 36psi, the upa are from wj with new bushings, the lca are aftermarket round tube. When putting new Polyurethane bushings on the leaf springs should I just burn the rubber bushing on the leaf spring and leave the metal housing there and introduce the poly busihng or should I just remove the whole bushing togeteher with the round metal housing and introduce only the poly bushing? After a couple of monhts of usemy rinde is a little softer on the front but the back needs a little improvement and since i havent replaced the leaf bushings I think its a good time to do it. Thanks for your help Link to comment Share on other sites More sharing options...
Motion Offroad Posted March 18, 2012 Share Posted March 18, 2012 Don't expect poly bushings to make the ride better. They last longer, but that's about it. Rubber bushings will ride better, and be a lot quieter. Link to comment Share on other sites More sharing options...
