Hi guys

So My liberty has been making an awful ticking noise and everywhere i have taken it they keep telling me its lifters or is sounds like a dead lifters, lazy lifers etc...
So I went on "http://www.trademotion.com/partlocator/index.cfm?action=getLocator&siteid=52&chapter=DP3043&appSectionid=10&groupid=10014&subgroupid=62065&make=17&model=Liberty&year=2002&catalogid=1" and bought 12 new lifters now I'm going to tackle this job myself has anyone ever done this if so some tips would be nice, now i dont' have the special too in the FSM "SPECIAL TOOL 8516" but do i need it i have been watching youtube vids of people doing this job on other cars with just a screw driver back yard mechanic style . If i do need the tool i think getting it from the dealership here for a day wont be a problem as my friend is a mechanic there.

Any info or tips would be nice if theres any out there

Thanks

Mark

8516 is the valve spring compressor

can get one for about 60 bucks, get the job done, and possibly sell the tool to a local mechanic

In The FSM 8516 is the Rocker removal tool, 8426 is the valve spring compressor hmmm....

Where do you get them?

I know here in Canada you can rent specialty tools from most of the major parts stores.

I would assume the same would apply in the states. Check with them and see.

So has anyone replaced or removed them on the forum? do I even need the special tool?

Haven't done it myself but I'm fairly confident in saying you will need the special tool. The special tool is a spring compressor and without it your risking serious injury both disassembling and reassembling the valve springs as they are under load.

I just checked and Autozone does rent tools so it would more than likely be in your interest to rent the tools to complete the job

I've used a small prybar/screw driver to do it in the past, and i've also beaned myself in the face too

used the correct tool on the two 3.7's i've messed with

Yah I went down to the jeep dealership here in town , I know one of the mechanics there, got to talking with the head mechanic and he said i could borrow the tool when i need it. Whats the job like any tips? Do i soak the lifters in oil before install, and should i bleed them so they can fully depress for install

Thank for the replys
