07 CRD w/ Heavy Bullbar - Suspension Issues? Old Man Emu on the line?

Good evening guys. Just for the record, I am pretty green when it comes to suspension and lift.

When I installed the ARB Bull Bar, I was aware that the suspension wasn't rated for that extra weight to carry around. Since that day, I put 15000km on the Jeep. (90% hwy). The reseller was suggesting to install OEM HD shocks that were meant to hold the extra 130lbs. I just though I should run the factory ones to the ground before swapping them.

I think the day arrived. Driving around town when there is little bumps or holes I can hear from the driver side front wheels a rattling/clunky sound from there. What could it be? I crawl underneath and tried to wiggle a bunch of different stuff but everything was feeling snug.

That brings me to my next question, if the shocks are gone, I'll replace them with good quality HD shocks that will last. Stiffer too. I looked at the Bilstein website but there is no load rating on their shocks. Anybody else? While I am changing theses shocks is it a good time to include a lift like the RR 2,25"?

Thank you for reading.. Any advices?

I read in Diesel Power that they switched out the front springs from their Grand with ones from the Commander Hemi. They also installed some new Bilsteins too.

Check your upper ball joints, grab the upper A arm and rattle it like it stole from you.

Waiting for the dealership verdict, I went back to the 4x4 shop where I bought my ARB Bull Bar to ask for their opinion.

We all agreed that they was no point to change something that wasn't broke but if the front suspension is going, he was strongly suggesting me a "Old Man Emu" from ARB (also..) suspension that gives also a 2" lift for the Jeep.

Anybody got knowledge or experience with that brand? Please share.

It's one of the old established companies catering to the off-road crowd. Unfortunately, they probably don't have anything for the WK Jeeps. Not under suspension systems. Check out their web site at http://www.oldmanemu.com/.

I didn't tried very hard to find it on the web site but I know it is available. A 4x4 outfit asked me 1195+5% for it.

It just sound very expensive to me! Unless feedback turn's out to be very good, I don't think I'll do the move.

You're going to need stiffer springs.

An alternative - expensive but less so than OME, is to get a set of springs from King Springs in Australia. They make 2 sets - 1 that is about 15% stiffer than "stock" and the other is 25% stiffer than "stock". Both sets are 1.3" taller than stock. (Jeep used about 12 different spring rates on WKs, so I don't really know what King means by "stock" rates).

They only ship via FedEx, so shipping costs are the same as purchase costs - about $US450-$US500 total. Init4Fun has an ARB w/ winch and a set of the 25% stiffer than stock springs and he loves them. (I have a set of the softer springs but have not installed them - waiting to design and fab my front bumper.)

Thank you for the reply TRZ. It look like a cheaper option than changing the whole suspension. But maybe in the long run for durability the Old Man Emu kit would be better..

Do you know if he only changed the front springs or all 4?

Just the front springs.

The info from the Diesel article was good. Problem is the author had access to Jeep engineers who could specify which springs to use, but Jeep considers spring rate information to be industry secrets, so you won't be able to just go to your Jeep dealer and ask for those springs. You'll have to guess which Commander (which equipment, which year) from which you want replacement springs. I'd probably guess 2008 Commander with Hemi, Tow Package and QDII (the heaviest Commander you can think of).

Jeep PN 52124207AA which are the 601 lb-in springs from the Commander. This was listed in the printed Magazine article I linked to earlier. Hope this helps.

There ya go. Cheap, middle and expensive solution for you. All should get you a lot closer to where you want to be. The King Springs will probably level things out for you (I just don't know if the 1.3" longer spring will over compensate for you).

I had OME on my WJ, got about 2.5" lift.
It was a better on rode ride than stock.
I hope to get the OME lift for my WK.
did he say he had it in stock?
my understanding it has not come to the US yet.

No they don't have it stock. They usually order once or twice a week from the warehouse. Last time for the bull bar it took them maybe 7-9 business days.
