I've already got the Crowns but I've read enough online to say I don't believe it makes a bit of difference which brand of the two you use. Their both good OEM replacements.

Tbone,
So your saying I shouldn't use the 3/4" spacer right?

 

He mentioned he already had the Crowns. Is that 1.25-1.5 over stock height with the Dormans, or that much over where your Jeep was sitting with the old springs? From what I understand, the Dormans have a lower spring rate than the Crown HDs.

 

No, actually if you want the rear just slightly higher than the front, I would use the 3/4" spacer and the 3/4" lift shackle you have. That should net you 1.5" front and 1.75" rear lift over stock. That would be 3/4 inch lift more in the rear than my picture shows above.

 

Yes, yes they are. Well, atleast stiffer than the 4.5" RE coils I had on my MJ prior to swapping the 3.5"

 

Got it. THANKS.

As far as the Crown/Dorman comparison it seems opinions are all over the board on the internet. I'd not be concerned using either. I went with the Crown simply because they were on the parts list the guy at Amazon used. Figured you can't fight success.

 

I Didn't see he had them. Easy to miss on this thread.

that height I gave was over the stock height. From the old springs it was like 2.5 to 3 inches.

 

What other components did you put on? How long you had the Dorman's on?

 

Hello Everyone,

Today I installed Rough Country 4 inch lift Rear leaf springs. When I bought the 99 XJ it already had the front suspension lifted, the rears appeared to be stock leaf springs with an added leaf to jack it up a bit. This unfortunately gave the appearance of a saggy rear end.

Today I managed to remove the stock leafs , (with a'lot of cursing and cutting )
The new springs are in. Everything looked great and the stance looks perfect now.

My problem started with the test drive, I'm not getting a vibration. It's more of a grinding metal on metal. The noise occurs when the car is rolling. If I put the car in Neutral while rolling I still hear it.

I thought it was a bearing, but this suddenly has appeared after my lift. I think it may have always been present, the lift has simply made the noise more apparent. My jeep is a 99 xj with stock (aside from the lift kit and a few other front suspension upgrades) Stock axles and driveshafts. I checked the ujoints, they looked to be ok.

I jacked the rear up again and spun the rear tires, I think I hear the sound, very faint of course. So I'm not sure what that could be.. I'll check the wheel bearings tomorrow.

I'm very new to Jeeps and learning how to make my own diagnosis and repairs. Part of the reason why I bought this thing, and now I'm sorta loving it. I've replaced a'lot of the engine components already, so it's running strong at 215k and has much love.

Any ideas would be appreciated!!!!

thanks!

 

Sounds like it time to put on a slip yoke eliminator kit. The driveshaft angle is most likely too great now that it is lifted. A TEMPORARY fix would be a transfer case drop kit.

 

It would be my first SYE install, giving that i'm a beginner but quick learner, do you recommend that I install the SYE with someone who has experience or I should be able to trudge through it?

 

When I did mine, it was a first time experience too. Look up some Youtube videos on it. They are a life saver. I had my transfer case out when I did it. It honestly was not bad to do but you need to have the right snap ring pliers to do it. What t-case do you have? Hopefully a 231.

 

I have a 231. Ok ... Good to know you were able to trudge through it. I guess I'll get some snap ring pliers next time in out ....

 

Also check the e-brakes & e-brake cable.

I had the lift put a strain on the pass side e-brake cable and it had the shoes always engaged....and gave the same rubbing sound since the side of the shoe was hitting the drum

Also had the e-brake cable rubbing against the rim edge at one point too, which is what shifted the shoes over inside the drum

 

What size center caps??The rims are 15 inch size,looks to be old keystone rims from what i can tell.Would gorilla caps be a good replacement?

 

Easiest way to find out would be to buy a caliper from Harbor Freight and measure it. Aftermarket wheels come in many different center bore sizes, so we could make educated guesses all day long and might be right... but what if we're wrong and you order the wrong one?
