just crossed 142,000 miles as we came home from Christmas in VA loaded to the gunwales. we're getting some creaks and groans now that i should probably address.
first order of business is over this past winter, and more so this winter, i'm hearing a lot of cracking/popping out of the front end when the steering is loaded up in turns, but ONLY when the outside temps are cold, like under 45. i've been over the tie rods and upper ball joints (still original) about a half dozen times and they've all got degraded boots but no discernible slop. i'm pretty certain its the idler arm, which connects the passenger side tie rod to the center drag link, which then leads over to the actual steering gear on the driver's side. the idler's located at the front and sees a lot of exposure to the elements, and the arm rides on a single-shear metallic-bushed stud. i think the cold temps open up the tolerances enough that during turns its starting to see enough movement that its becoming loud.
new one on the way compliments of Moog, and because i can't leave well enough alone and we plan to do more adventuring, i'm upgrading the mount with a Calmini Idler Brace. it'll reinforce the arm on the bottom as well as provide a higher level of rudimentary protection in the event we nose into a rock or log jam.
if that doesn't do the trick, i'll move on to new tie rod ends and drag link. there's enough slop in the steering that frankly, its time anyway.
second item is giving me a harder time tracking down. when its been driven for 20-30 mins there's a prominent pulsing to the braking and on/off groaning in the brakes that's timed with the wheel rotation. its not warped rotors, there's no sensation in the steering like that. but a definite on/off grinding feeling in the brake pedal that points to a rotating part of the assembly. i greased the caliper pins with no difference and the rotors/pads look great. i think the (original) rear drums and shoes are either shot, or we collected some mud/grit in them during the last river crossing and its created some deposits that maybe i can sand down. i really hope its not a rear axle wheel bearing, but i don't think that's the case since the noise only happens under braking and there's none of the typical droning/humming aside from tire noise. i'll have to get it up on jacks and try wiggling the rear wheels around to confirm.
yay 2019 old car problems!
