We have a 2005 Grand Caravan. I've replaced the steering rack before due to the driver side being worn out. For the most part the job was pretty easy. Take off the sheet metal support off the bottom of the aluminum engine/trans cradle, then a few bolt holding the rack in, and disconnect the steering colum. It took me a couple of to get the lines disconnected because the are so tight in there on top of the aluminum cradle right next to the rear engine mount.
This rack has worn out too. Is there any trick to taking the lines loose so the rack will drop out of the cradle? Maybe a 12-point line wrench?

What is worn out on the rack? Unless it's leaking I have a hard time understanding "worn out". If the inner tie rods are loose, that's all I would replace. That can be done in the vehicle.

Wish it were just the inner tie rod, but it's not.
The bore of the aluminum rack is worn out from the rack gear sliding in and out. We have a side load garage and a coarse concrete driveway. So my wife is always making a full right turn to get into the garage. The rack gear is fully extended wearing the inside of the rack out. It's leaking at that spot also.

I use a lot of crows foot line wrenches that go on a 3/8 ratchet.They will usually let you get to the lines pretty easy with wobble extensions and or impact swivels.Then I use mostly stubby wrenches to finish removing them.After doing a bunch it gets a bit easier.Some GMs you basically had no room to get to the fittings and they worked for me.Rocky

If you take the emmisions canister (3 bolts) out of the way you can get to lines very easy with a wrench.

Thanks for the tricks and tips guys. Sounds like a good plan.

I have cut the metal line in a convenient place and used a compression union to reconnect it. Has always worked without a hitch for me.
