chopper35nj Posted October 3, 2023 Share Posted October 3, 2023 Good morning CC members. It's been several years since l have posted in here (testament to the reliability of our little rigs), it's time to refresh the steering on my 89. I know it's been covered but l'll be damned if l can find the write ups on ZJ steering conversions. Simply put, l need to know what parts will fit the 89 D30. The most economical solution seems to be complete or semi-complete kits. I know that the heavier duty V8 ZJ steering links will fit but what about the ball joints? Most of the kits come with ball joints, l just want to know if the parts will interchange before l pull the trigger. Link to comment Share on other sites More sharing options...
ghetdjc320 Posted October 3, 2023 Share Posted October 3, 2023 Grab the spicer/dana ball joints and the moog ZJ tie rod. The rest or the components such as drag link and tie rod ends just use moog replacement MJ/XJ parts. The ZJ tie rod is where the strength comes from. Ball joints are the same but best to grab the spicer ones. Link to comment Share on other sites More sharing options...
cruiser54 Posted October 5, 2023 Share Posted October 5, 2023 How about the steering box off a ZJ? Link to comment Share on other sites More sharing options...

The ZJ box could be an upgrade depending on what you’re looking to accomplish Link to comment Share on other sites More sharing options...
cruiser54 Posted October 5, 2023 Share Posted October 5, 2023 I did it on my 87 MJ. Quickened up the steering input. I liked it. Link to comment Share on other sites More sharing options...
zomeizter Posted October 6, 2023 Share Posted October 6, 2023 Durango steering box is the upgrade IAW with the XJ club, but if the ZJ box improves things then why not... Link to comment Share on other sites More sharing options...
gogmorgo Posted October 6, 2023 Share Posted October 6, 2023 The Durango box is a strength upgrade, but at the cost of range of motion. It doesn’t turn quite as far, you’ll have a marginally increased turning radius. Likely won’t be the end of the world, especially if tire rubbing already limits your range of motion. The ZJ box isn’t really a strength upgrade. It just has a quicker ratio, meaning you get more steering angle out of less steering input. It shouldn’t result in a change in turning radius, but you won’t need to turn the steering wheel as many times to go from lock to lock. Link to comment Share on other sites More sharing options...

75sv1 Posted October 6, 2023 Share Posted October 6, 2023 There are 'stops' in the Durango box that can be removed. I did rebuild one. I have not installed it yet. Probably going on the MJ. Thinking of an SJ box for my 01 XJ. Link to comment Share on other sites More sharing options...
cruiser54 Posted October 6, 2023 Share Posted October 6, 2023 The ZJ box in an MY or XJ feels like it's the box they shoulda had in the first place. Link to comment Share on other sites More sharing options...
