Wrangler suspension question

[Germy]

My friend bought a yj, the springs are completely flat and the shackles are twice the size of mine. Why are springs flat?

 

[Torxhead]

The oem spring shackles were a bit longer than those of the CJs and the springs were flatter. I am sure this was to soften the ride up. By now I would think the springs would be in need to be replaced.

My guess is their worn out from time. Wrangler springs are 1" longer and a 1/2" wider in the front than on a Jeep. Their shackles are 4" between bolt centers instead of 3" on a Jeep.

Another wrangler ?, looking for two fenders for a 95. I see them at morris for 175. Tried junkyards. Any thoughts? Been cruising craigslist, anyone have some let me know

Factories intentionally make leafs as flat as possible for ride and articulation. A flat spring grows the same either compressed or extended, a greatly arched leaf will be near impossible to compress anywhere near flat and when it does it grows in length hugely out running the shackles ability to compensate. Long shackles (fangs) flex a lot creating their own stability and leverage on frame issues. Thus the invent of the coiled wrangler. Also consider that many run a SOA setup to eliminate the lift kit arched leafs. Personally I wish my CJ was SOA,ed and not Procramp sprung.

He has 7 inch shackles and 31 rub under flex. I understand the flat concept, but something is up

Assuming it hasn't been messed with from stock and springs moved side to side at some point, the pass. rear will usually get the most wear of the four springs. How much distance between the top of the axle tube and bottom of the bump stop on that spring? If you have 3-4" you are probably fine. YJ springs were fairly flat but still had some arch to them. The bump stop distance is the best way to quantify exactly how worn they are.

Cool, I'll see him tomorrow. Thanks

Another question. His front is a 30 and i would assume that the rear was a 35. The weird thing is that on the cover there is a rubber plug? Is this normal? 95 sahara l6

Yep -- Wronglers (sorry, I can come by that honestly...I used to own a WhyJ ) had rubber plugs in the diff covers, instead of steel plugs.
