My jeep has 240K and Iíve owned it since 70K and never touched the front suspension. Is there anything I would be stupid not to replace at the same time? Im ok with going back in after and replacing easy things later, but anything that has to go in when the new shocks are going in, I want to do.
What can you guys tell me about those parts? I think I recall the UCA is easier to replace entirely, while the LCA can simply have the bushing replaced. If so are either job difficult to do? Looks like a couple of bolts on the UCA and is the LCA bushing hard to deal with?
You'll definitely want to replace the UCA while the strut is out, since you can't remove the bolts while the strut is in place. It's also easier to get the strut in and out if you loosen the UCA bolts first, since you'll be able to push it up and out of the way more easily.
The LCA has a fairly accessible ball joint, but you'll need a ball joint press to get the old one out, and to press the new one in. You can rent one at most auto parts stores if you don't want to buy one.
Since you're doing all the work and will need an alignment anyway, you may consider replacing your outer and inner tie rods. When your front end is off the ground you can try to wiggle them and see how much play there is.
Finally, take a look at the condition of your half shaft boots. The half shafts are easier to remove with the front end apart, so if they need replacing, this would be a good time to do it.
As far as tearing the front end apart, since you're replacing everything anyway, rather than tying the spindle to something to keep stress off the brake line, I'd recommend removing the caliper altogether. You can use a hanger or a bungee cord or something to hang it somewhere secure and out of the way and you'll have a much easier time removing everything with it out of the way.
