Dealer can't fix truck, what do I do next?

Made the upgrade yesterday to 315/75R16's to replace my pretty much used up 285's (fresh snow here yesterday was pretty much the nail in the coffin :) ). I mounted them on the stock 16x8 alloy wheels that came with my truck. So far so good-I don't have a levelling kit yet (still making my plans as to which way I'm gonna go) and I haven't managed to make contact in the wheel openings yet (even with my Putco SS running boards although it's close). However the same doesn't hold true for the upper control arms. I was prepared for this from other's posts on here as well as my experiences with my XJ (downsize Cherokee for those not versed in Jeep vernacular). When I added 31's to it I got the same results. A simple adjustment of the steering stops cured that-although at the expense obviously of turning radius. Probably the same thing will come for the Silver Cloud this weekend as a band-aid fix-I was just too lazy last night after the install ;) (gotta give me points for honesty though). I'm not as hung up on the factory wheels themselves as I am of maintaining the stock offset-my Jeep experience is that wheels with greater offset wreak havoc on the unit bearings. And our Rams are the same basic design-larger bearings for sure but also a lot more weight sitting on them... . will it handle it? I dunno-don't really want to take the chance. At some point in time I'd like to have a reverse-cut 60 slid under to get rid of the CAD and gain some axle shaft strength as well as the strength benefits of the reverse-cut gears-oh yeah locker might be handy too... but I digress.



What I'm getting to in my round-about way is that for my XJ there were manufacturers (although they escape me now) making lower control arms (the offenders as far as tire rub) that were doglegged/boomeranged/however you want to put it. They were bent towards the centerline of the Jeep to allow for more clearance anyways. So has anyone run across anything like this for a Ram? Everywhere I look on the 'Net has super-beefy control arms out the ying-yang-but all of them are straight. By the looks of things it's the UCA on the Ram that's the interferer. Even with its proximity to the frame and the brake hoses and wires that attach behind it, I'd say you could get away with a bend inwards of an inch or better. That would allow for quite a bit more tire pivoting...



And while I'm at it I'd like to get these magic arms made similar to the Tera arms for Jeeps-they are adjustable for length to allow the axle to be adjusted fore and aft in the wheelwell, as well as permitting greater caster adjustments than what the factory adjusters allow. I'd also like something with either a soft poly or factory rubber bushing to keep road noise transfer down-although on a full-framed vehicle like the Ram that's probably less of an issue than my uniframed XJ.



So am I looking for something that doesn't exist? Or can anyone point me to a place that might possibly make something like this? I could probably get it done up here if I used some of my oilfield sources-I have a few friends who are B-pressure welders and I do have access to various means of NDT (X-rays for welds, mag particle inspection, etc. ) Probably could get the tubing bent as well I guess. But I'd just as soon buy them premade-I seem to be short on time to get the stuff done that I actually have sitting around home-let alone trying to fab up something else! :D



Thanks in advance

Save yourself some money and buy a Skyjacker complete 2 1/2" lift kit and don't install the add a leafs unless you need them. The best price I found was through www.jackit.com.

I also have the DT trackbar and it is a high quality part. There phone #888-776-2403. Sam
 
I'll probably end up with the Skyjacker springs up front-questions about them are in another post :) . But I don't want to run their shocks-and I'm not lifting the rear anymore than it already is. At 6'1" I have a tough time seeing into my toolboxes already! (On the bright side it does work like an anti-theft device for short people :D ).



Still haven't given up hope on finding boomeranged control arms yet though... .



Jason
 
I also run 315s and have the same control arm problem. I've just learned to deal with it. I've seen older Broncos where a piece of tubing was installed to 'smooth out' the offending lip on the control arm.



I don't think we're going to have any luck with boomerang control arms for our trucks - just not enough demand. Cepek used to make a long arm kit - not sure if it's still available. I think my solution is going to be 19. 5" wheels so I can get a ~35x10 tire and eliminate the interferance.

I'm gonna have to deal with it for a while I guess-but I'd sure like to find some sort of long-term solution. I hate having to "settle" for something-ask my bank account all about that :D I should have gotten personalized plates that read "MONYPIT" instead of "SLVRCLD".....



I'm pretty sure that the rub wouldn't be as noticeable with tube-style control arms-because of the lip that you're talking about... but I still think that the boomerangs would be the hot ticket. Got days off coming-may have to BS some of my welder buddies to see what is possible. Wonder if we have any pipelining coming up in our area... free X-raying would be nice! ;)



And I'd love a set of 19. 5's too-I'm sure the rubber would last forever even with all the gravel driving I do. But I don't want steelies-gotta be aluminum for me. 'Member what I just said about settling? Seems to be easy to find aluminums for the 3500's-not so much for the 2500's. Maybe I'm just not looking in the right place!

3 weeks or so with the 315's on now....

... . and whaddya know they haven't magically cleared the control arms yet! :D Looking at the rub marks yesterday-apparently they touch the lowers slightly too at full lock-although not as much as the uppers. Looks like the stockers are 2" wide or maybe even a little more. So if some of the aftermarket ones are smaller diameter (say 1-1/2") that would restore some of the missing clearance-as well as losing the protruding lip that causes most of the ruckus. But I still haven't given up hope of finding exactly what I want-although I suspect I'll have to "settle" for something for now... . :rolleyes: . I'll make my final plans I guess when I actually level the front.

I put my 315's on Saturday with 16x10 wheels and they rub real bad. I just oredered a 4. 5 skyjacker kit (very pricy). But forgot the steering stabalizer, how important is it to put on right away. Hoping to save up some more funds first but if I can't I guess I'll have to bite the bullet.
 
Hey man-just posted to you on the thread about tire sizes... . didn't realize you were running on wider wheels. Must have a pretty good positive offset? I'm running on the stockers-and with the clearance (or lack thereof :cool: ) between my running board flaps, Sport bumper trailing edge, and tires, I couldn't run anymore positive backspace. So instead I rub the control arms-better trade for me anyway. My truck is on the verge of being too tall for work now as it is-I'm 6'1" and have a hell of a time seeing into my toolboxes when the ground slopes away a little.



But about the stabilizer-I don't have any experience with lifting a Dodge (until my levelling springs and misc. parts make their way here and I get my lazy *** in gear to put everything in :D ). But I do have experience with the same basic suspension design on a smaller scale. My Jeep Cherokee is real similar in design. When I lifted it 4. 5" I never bothered to look at the stabilizer... bad error. It was completely toast-and so I got to find out first hand what the "death wobble" that I'd heard so much about was all about. At 90 km/h it shook bad enough to literally blur your vision :eek: . 1 steering stabilizer, 4 new tie rod ends and a new toe setting later and the problem was solved. My stocker is still hanging in now with the 315's-and of course the truck is new enough that all the steering parts are still relatively tight. But I'm wanting badly to get a dual Skyjacker setup in there for peace of mind if nothing else... . I'd spring for some sort of beefier stabilizer if I was in your shoes I think.



Just out of curiosity where did you order your Skyjacker stuff from? NSOR? Priced there a couple times before and they were always a little cheaper than Modern Motors in Calgary-but I've never ordered anything from them. Tried to access their site tonight but keep getting nasty error messages-maybe tomorrow.



Hope this helps man

Stefan,



What tires did you go with?



As far as the SS, I would at least have one on the truck (I have no idea if the 4. 5" Skyjacker Kit retains the stock SS, if so run that for now). IMO, a good SS prolongs the life of other steering components.



Also a weak SS has been believed to be the cause of the notorious death wobble. I'm sure you want to avoid that.
