Finally got a few things on our '11 Ram 1500 done.
The vehicle has had a crazy wobble at speeds for since we put XD 20" wheels and General Grabber AT tires. I did an Eibach 2.5" spring and strut change this summer along with a steel aftermarket bumper and some wire brushing and coating on the front part of the frame. When I had it aligned the camber was visually positive but drove straight enough although it had a decent shimmy about 60-75mph. I had my son take my 2500 back to college so I could have time to figure it out. Once I looked into it, it turns out the LCA bushings were frozen to the bolts. Ended up just getting new LCA from NAPA, spindles from MoparPartsGiants (they were corroded badly when pulled the hubs from them this summer) and UCA from JBA Off Road in PA (really nice people) to get the caster back in spec with the 2.75" lift.
Getting those LCA bolts cut was pretty hair ball with a 7" cutoff wheel on my angle grinder and the truck on a jackstand. Sawzall blades did absolutely nothing. After it was all installed and the front wheels/tires re-balanced it goes down the road pretty nicely now. (still a little shimmy at 70/75 but could be from the tires not wearing evenly and being 35" Load E rated). BTW - all the suspension bolts were heavily covered in Anti-seeze as I wouldn't want anyone to deal with the cutting bolts like I did.
Also the last time at the dealer, the Ram tech said it needed a new rear caliper and it would be $700 to replace (for 1 caliper!). I was like I'll just replace the whole damn rear brakes system myself when I swap the Bilsteins shocks I had ordered for the front. As soon as I pulled the fender liner out and saw a bunch of rust covering the frame I was like f##k it got some more to do. I prepped and treated the sections I could get to with POR15 rust covering and POR15's Top Coat. I'll get the whole truck undercoated down the road. I know a guy in north NJ that does Waxoyl applications but was also thinking a LineX product or seeing if NHOU (
https://nhoilundercoating.com/) has a nearby applicator.
It still needs some rocker panels and some other little things so probably more work than it is worth but it's a 5.7 Laramie crew cab with 110k miles and for the price of new trucks at least most of the running gear is good for another 100k.
PS - I ran out of POR15 on the first side and used some Rustoleum brush on primer. Might be a good test between the 2 treatments.
So the ask your auto mechanics questions:
- is anti-seaze worth it and if so what's you favorite to use?
- what chassis treatment do you recommend?
