I just purchased new Koni Evo 99B 3254 Shocks for the front end of my 2006 Intrigue. I am getting tired of waiting to have a shop install them (everyone is busy down here). It looks like it might be an easy install, but I don't want to crawl underneath and run into problems. Anyone have any recent experience on installing the front shocks on their Country Coach?

Yes, I changed the shocks on my Inspire last year. Not really any different, or harder than installing shocks on a pickup truck. The fasteners are larger and require more torque, do you have the correct tools?

where is down here?.

I purchased mine over the internet and had them installed at a 18wheeler shop (rush truck center). they were busy but turnaround was 2 days, could have been faster if i would have scheduled the service vs just showing up.

If you turn the wheels all the way to one direction you can gain full access to the shock .Loosen the nuts then use a narrow ratchet strap to compress the shock until the bolts are free then pull the shock. reverse the process to install. Make sure you torque to spec. They need to be tight or they will rattle.

Changed to the EVO's in 2016. No problems, just takes some bigger wrenches and brute strength.

I live near Colorado Springs, and I have a 1/2 inch drive torque wrench, and some other 1/2 drive hand tools. Do I need an air powered tool to make it work?

The shocks came with no info on the torque specs.

no air needed. I seem to remember 1 1-1/16 and a 1-1/8 socket 12 inch extension and breaker bar. I think if was a 3/4 grade 5 bolt. Takes about 15 minutes to do a shock if all the tools are gathered

My Neway Holland IFS on 2007 Allure shock torque specs are 90-110 ft-lbs clean/dry.

Bolts are 3/4-10NC, Grade 5.

It is called out in the Neway Holland IFS Series Maintenance manual for my IFS.

EDIT: Recommend replacing the 3/4 -10 Grade B lock nut (QTY 4), or the correct one for your shock bolts.

PS - I replaced out my Koni adjustables with EVO99 and am very happy. My coach front weighs in about 12,000 lbs.

Changed mine, front with Koni Evo 99B 3254 last month no problem. Had to lower air so shocks were not extended to far, and use jack stands for safety.

Pretty easy, loosen 4 nuts and as others have said.

There is no secret to it at all. Also this is an any truck shop thing if your not comfortable doing it. It is literally a 15 min job

I finally went to work on the shock absorbers after getting some labor quotes that I felt were too high at the local shops. After using a breaker bar and ratchet, in a very tight spot, I got the first one off.

I used a 28 mm socket that fit just right on the head of the bolt. The standard 1 1/8 inch socket fit a little loose.

Now I want to replace the bolts but not sure what material the bolts and washers and nuts are made of. Should I try and go with Stainless, zinc, or what?

If you take a pic of the head of the old bolt we can tell you what it is, assuming it is not to rusted to read. Other wise, i personally would use a grade 8. Yes, a lower grade would probably be ok but why risk anything for two cap screws.

IASM · 10-14-2019, 09:44 PM

when i replaced mine i used grade 8 yellow coated bolts and nylock nuts.I bought long enough bolts to ensure the shoulder of the bolt made contact with the shock and the mounting tabs. This required a longer bolt that i cut off. I added a thick steel washer to allow more room for the thread. The reason i did this is i noticed thread wear on the old bolts since part of the threads were in contact with the shock. Hope i explained in a way thats understandable .

Having worked the hardware department for many years at Home Depot, I know that if there are no markings on the bolt head, it is a standard grade 2,(and probably not suitable for mounting shocks). 3 small tick marks on the head corresponding to every other wrench flat indicates a grade 5. The highest strength bolt, at least for automotive use, is grade 8 which has 5 tick marks on the head. And there are corresponding nuts and washers for each bolt grade.
