Car Forum / Jeep / January 200787 XJ rear leaf springs
My DD is a 87 XJ 4.0 auto. I have broken rear leaf springs on both sides. I have an 89 XJ for parts. Should I change the springs or the springs with the axle? The axles should have the same (or close) ratio so that is not an issue. Merrill Changing just the springs should be OK. Use new U-bolts. > My DD is a 87 XJ 4.0 auto. > [quoted text clipped - 3 lines] > > Merrill Thank you Matt This might be the easy way. I had planned to swap axles and replace the bolts and bushings.

That means mileage on gears, leaks or seeps of oil at the pinion and at the axle ends, brakes and brake hardware, etc.... I am thinking on doing the same thing with my 88 and 87. The 88 has new springs and brakes, but more miles and no leaks. You need to be sure the gears are the same too or you will not be able to use 4x4. You can check the gears by jacking up one rear wheel and marking the tire and driveshaft with chalk. You then turn the wheel two turns while counting the driveshaft revolutions. You can just do one turn of the wheel and double the driveshaft revolutions to get the ratio. If you jack up both wheels, then it's a one to one count, but with just one wheel turning it's a two to one.

The 89 has about 200,000km and doesn't leak so I had thought I would probably use it. I'm not sure about the brake shoes or drums, but the 87 has good parts if I need them. Both are auto so I assumed the ratios would be similar. I had planned to check anyway for the few minutes it takes. I only use 4wd to get out of bad situations and not for highway cruising. Would that still be a problem if the ratios are not identical? When I disconnect the driveshaft, can I expect any surprises with the universal joint? Most are easy and some are pigs. I have never disconnected an XJ driveshaft. Merrill > Which one is in better shape?

It will list all kind of information you will need. http://www-5.jeep.com/wccsapp/universal/J/index.jsp?appStr=wccs&titleStr=Contact +Jeep&familyStr=brand&franchise=J&actionURL=%2Fwccs%2Fbrand_forms%2Fus%2Fwebform .jsp&promotion=null&category=U > The 87 has about 300,000km and works well with no leaks.

I want to get a build sheet for all 5 of my Cherokees including my old DD, 2 fixer-uppers and 2 parts donors. If I can't do it online, what should I ask the dealer for? My parts dealer Town and Coutry Chrysler (highly reccomended) in Smiths Falls is open late on Wednesdays so I could go there after work this week.

Wait. His `87 was built by AMC, not Chrysler. Are build sheets even _available_ going that far back? -- "I defer to your plainly more vivid memories of topless women with whips....r" R. H. Draney recalls AFU in the Good Old Days. Yes Lee I had thought of this, but my next thought was nothing ventured nothing gained. Because of a medical emergency in the family I haven't got around to it yet. My 84, 87 and 89 could be a problem but my 91's are Chrysler products. I thought I would try it online and, um, ...LIE! as recommended because I'm not sure I can get to the dealer this week. I will advise the group with the outcome.

Go to the stealer and get all new straps for the U-joints. They use flat metal straps and re-using them is not a good idea. > The 87 has about 300,000km and works well with no leaks.

I know of a couple that got a surprise then they unbolted the Universal Joint depending on the park to hold the car from rolling, and one that will never make that mistake again. Buy a saber saw for your spring hangers and U-Bolts. Wire bush the ratio tags bolted to their covers, Trailer packages and SMOG requirements make for many ratios.
