Replacing Shocks and Struts

I have a 2011 CM 5.7 2WD, and after 180K miles its time to replace the Bilstein 4600 front struts and rear shocks. I have the correct replacements in hand but these were not "kits" so they did not come with replacement bushings or retainers. The replacement shocks and struts both came with new nuts for the threaded shaft. Is it necessary/required to replace the bushings/retainers if they are still in (visually) good shape? I'm in East Texas so my truck doesn't have any underbody rust or other corrosion. I don't want to start the replacement process just yet if I need to replace additional parts I haven't ordered. TIA

 

On a related note, at 180k should I be looking at additional items like UBJ, LBJ, tie rods? I've never owned a vehicle with more that 90k miles before, so this is new territory for me. I replaced one of the front wheel bearings earlier this year and the steering still seems a little loose / wanders slightly.

 

Depending on what you bought, you will most likely want to purchase new bushings for the rear shocks (you can reuse the washers) and new top hats for the fronts. The bottom bushings on both front and rear come installed on the shock absorbers so you just need parts for the tops.a KYB top hats are popular and affordable; I’ve used them on several sets but the bushings started to split after 30 or 40k miles on one set. The others have been fine, though. Rear bushings can be had from Toyota. I haven’t found a good aftermarket replacement - the part numbers I’ve gleaned from other threads ended up being incorrect or for - 1st Gen even though it was posted for a 2nd Gen.

As for reusing the originals, I wouldn’t bother with the original top hats at that mileage. The rears may be serviceable but are most likely hardened or cracked. I reused the rear bushings a couple of times (despite trying to locate aftermarket replacements) until my most recent setup came with new ones.

I would suggest having the front tie rods inspected, particularly the outers. Mine were worn at around 190k miles and causing some uneven tire wear. It’s also not a bad idea to give the ball joints a close inspection.

 

Thanks! I felt that replacing the bushings would be a good thing to do, but hadn't considered replacing the top hats on the front. I'll prolly stick with Toyota parts. I'll check the ball joints when its in the air and will have the tie rods inspected when I take it in for the next alignment.
