    Hello, I've heard that you can get kits to rebuild your steering box yourself, but from where? Also it making a popping noise. Maybe I just need to buy a new one. Just need to rebuild or replace.

    For TRW input seals, the part # is TAS000001. They are faily easy, you can get that and most dealers and parts places. Getting the seal in and to the correct depth is the hardest part. As for the whole thing, you can order a kit from anyone who sells TRW boxes, but I caution on doing it yourself. It is not a hard job all in all, but it is very easy to screw up too. TRW has some good instructions on thier website, but they need to be read, understood and followed very well. Things need to be very clean and things need to be checked very closely.

    When you use re-builds its very important to make sure it's just the seals that are leaking. And why the seals failed. If the are dry rotted and worn a seal kit may do the trick. But if they are worn and torn, buy a new box don't play around. If the worm gear is slightly off it will ruin the seals within a matter of days/weeks. And a re-build kit will not get rid of excess play like a new one. I've done it both ways and both have worked. But the kit can give people problems if the issue is deeper then a seal kit.

    Steering gears aren't something to be messing with if you don't know what you are doing. You are taking total liability in your hands if something goes wrong. This is steering you're playing with, not clearance lights or chrome hub caps. Like Largecar said, most seal leaks are due to worn or scored parts that installing a new seal will not fix. Rebuilding of a steering gear is not for a do-it-yourselfer!!! I understand we all want to save a buck, but this is one area I highly recommend to just buy a complete reman gear and install it. Changing a gear is certainly something you can do yourself and save some money. Shop around for a reman gear. Get a reman gear with a warranty, install it, and get back on the road. Don't waste your time patching a worn out leaky gear.
