Greasing Leaf Springs?

I was researching the other day and came across a discussion wherein a guy recommend jacking up the Jeep, sticking a pry bar between the leafs and packing them full of grease. He said that he did it and his bouncy ride significantly improved. Do you guys/gals add grease between your springs? How do I know I'm not going to wreck something by prying the springs apart? I've tried looking around the web but couldn't find answers I'm comfortable with.

This is my first YJ and I'm not sure if it is riding correctly or not. I've been contemplating new shocks. I know it's not supposed to be a 'nice' ride but is it really supposed to be this bad?

i don't grease my springs, i don't think it would really do much for the ride quality. grease is usually used to reduce friction, i don't think there is that much friction in the springs that they would need greasing. also they are not sealed so i would think that the grease would get washed out relatively easily driving in the rain or a muddy trail.

what kind of springs does the jeep have? are they the original springs? how about the shocks, could they be worn or need replacing?

That's one of the things I thought of too. It seems like it would get washed out and/or attract grit.

1995. I believe the springs and shocks to be stock. The PO's never wheeled. It had street tires on it when I bought it (found the receipt - they were installed in 2001!). It lived in a garage...<50K miles when I got it a few weeks ago. The ride is definitely harsh. The springs don't squeak or anything but I figured if other people are greasing their springs I should try it before plunking down the cash for new shocks. I'm contemplating a lift next year pending WAF and don't want to waste $150 on something that may be replaced so soon.

what were you driving before the jeep? b/c jeeps (especially cj's and yj's w/ leaf springs) ride significantly rougher than other vehicles. that could be the problem, or it could be that the shocks and springs are very worn.

A boring, reliable, sedan. I've been meaning to have my neighbor take my YJ for a test spin. He's owned his for ~10 years. Maybe I'll start there.

did the jeep have a hard top on it? many years of a hard top can flatten the springs out. thus reducing their ability to "spring".

I have an 89 with 94,000 and the springs are fine. When the ride didn't feel right I replaced the shocks and its fine. The 89 rides more harsh than my 06, as expected because of the coils. The leaf springs are a rougher ride. Unless you can do it yourself expect to pay 1,000 to replace them. Never off road with 50,000, you need shocks.

as you can see by my avatar, i drove an oldie on tour in sedona. i got better tips from tourists partially due to the ride. when off road with the coils, people with weak stomachs tended to get sick. mercedes parts just don't belong on a jeep.

No hard top. Still has the factory soft top.

kik - so the shocks helped your ride quality a lot at ~94K? I've driven on leaf springs plenty of times but it's never been anything other than a full size vehicle or truck. Should they feel similar to that? We were initially inclined to name her 'pogo stick'.

The springs aren't sagging too bad, right?

Just a little one for the time being...

i'm no auto mech(only helicopters) but your springs look pretty flat to me...... nice looking jeep. can i have those doors? save me the time i'm gonna spend painting the green ones my neighbor gave me. lol i'd like to see some more curve in the springs. some heavy duty shocks might do the trick. mike

My springs look exactly like yours and I don't have a problem. Replacing the shocks solved my problem. The old jeeps ride like trucks, that's about it. Your jeep looks like its in great shape. If it never went off road you should not need springs, unless you want to change the ride with something after market and spend the cash. After 50,000 miles the shocks need to be replaced.

I definitely lucked out when I found it. I was going to get a 4.0 but couldn't say no to the mileage.

Pending my neighbor's ride evaluation I'm inclined to give it a set of shocks and see what that gets me. It definitely does not feel anything like a truck. What kind should I be looking at from a value perspective?

it couldn't hurt to replace the shocks, they are probably due to be changed any way. i wouldnt got with OEM (mopar) shocks though. OME (old man emu) are the best shocks out there from what i hear. Rubicon Express is good too.

Good to know about the OEM. Might anyone be able to recommend anything cheaper than OME or RE though? I might be getting a lift next year if I end up enjoying this hobby as much as I think I will. What if I just went with some SkyJacker Nitros for the time being?

My WAF is low(!) right now. I've put myself in the dog house at least once per week since getting this thing. I told her that I wouldn't be doing anything to it for at least six months. And yet, I've added wheels, tires, bumpers (which I am now reselling so I can make my own), air filter, rotor/cap, wires, plugs, fuel filter, new injectors, a 4.0 TB, revised cab lighting, and many more little things. Still on the list - a receiver mounted bike rack and a receiver basket. This is my second expensive hobby...I've already been teetering on the WAF for a long time.

Just a comment on the springs again. They don't look flat at all. I think some people are saying it because of the angle of the photo.

how do these look?



your springs look ok, but any spring 14 yrs old will be a little tired, the weight is on the jeep wether its driven or not.

but they look suprisingly good. shocks will improve your ride. but if you plan on doing any kind of lift, do it at once, lift springs and shocks.

Woah, I'm glad they don't look like that! The WAF is going to be a tough one on a lift right now. It's just not going to happen any time soon if I'm holding out for a full kit. I'm concerned that if the ride really is as rough as I think it is I'm going to be putting undue strain on the vehicle while holding out. Right now, believe it or not, the ride is entirely squeak/rattle free but for an undiagnosed, intermittent, slight squeal in the right front that sounds like the warning tab on a break pad (the pads are fine though). I took the entire dash apart last weekend and put pads on the back of every screw. I then pulled the consol box and collected all the change that had accumulated between the upper/lower sections. I've also oiled or greased everything I could think of. All I get now is wind noise and a LOT of treble. Oh yeah, and the clunk, clunk, clunk as I roll over the seams in the road...which I guess is what started this thread.

Im just lookin for a newer set of springs, mainly because mine are starting to flatten out a bit, would a shackle lift be any good with tired spring packs? or would it only make it worse? what about shocks replace and it get better?

87YJWrangler - I think if your springs are worn out you should get new springs rather than a shackle lift.

I've decided that I'm going to ask the wife for a lift kit. Pray for me. Looking at the 2.5 RC.

Just got the last numbers to finish our taxes. Swell timing! We were just talking and she asked me how much the shocks would be. She didn't flinch when I answered $400. I had to tell her the truth afterwards (truth = shocks + lift) but I'm thinking that the lift might actually happen. Of course, she is negotiating for a new patio and some refreshed landscaping...

I think she secretly likes the idea of the lift but is not willing to admit it because it erodes her negotiating position. She can spot a stock Jeep and say 'I do not like that one, what is different about it' as fast as anyone can.

I've tried telling in the past. Wish it worked.

Ha-ha. She's in. The lift is a go with a smile on both of our faces.

BTW...I figured out why the ride quality was so bad. I checked the tire pressures yesterday and all of my wheels were between 45 and 50 psi. I'm guessing the PO of the tires was trying to improve his gas mileage. Taking them down to 27 made a huuuggggeeee difference.

cool dog...

if you want a better ride, you gotta change you blinker fluid and air up your tail lights first, then grease your leaf springs


BTW it is easier to ask for forgiveness then to ask for permission

For the record, there is plenty of documentation on the web about greasing leaf springs. 'Grease Leaf Springs' comes back with 72K hits on Google. Most of them pertain to other vehicles - hence my question here.
