Do lift kits affect the longevity of the FJC? - Page 2

If you go with a moderate lift (2"), you will not need the diff drop. The diff drop does keep you from putting on a new or different skid plate, which might cause more problems. You have to consider all these things.

Thanks for the info, I was unaware of that. Will the factory skidplate still work with the diff drop, or does that have to be removed as well? I am speaking of the standard black steel (functional) skidplate, not the optional aluminum one.

Also will a 2" lift accomodate a 285 tire? It seems that w/o a lift that's not likely but those with 3" lifts are saying the tires clear fine. I am going to purchase the adjustable donahoe coilovers for the front so I can get any lift I want up to 3", but if 2" will allow the 285's w/o issues then that would save me the trouble of a diff drop and suit my purposes perfectly.

Thanks,
Alphonse

Does installing a new suspension system (i.e. Old Man Emu) effect the longevity of the CV Boot? How long will it be before the CV Boot dies? How much does it cost to replace one?

Not to mention that a diff drop voids a warranty just as well as a lift kit.. I rather have the warranty voided on my CV's than my front diff and front drive shaft..

Tankota, I see in your profil that you are running a similar lift to what I am considering. Would you mind telling me what height you keep your lift at in front, what size tires are you running, and did you have to trim the body mounts to squeeze them in?

Thanks,
Alphonse

My front lift is at about 3" right now, it's kinda set for the winch bumper which isn't on there yet. I'm still running the stock tires right now, and I've already trimmed the body mount. Yeah, I know, not much help...

I put the Toytec diff drop on today, my skid plate went back on just fine. Toytec gives you 2 bolts that are a bit longer to reach the back 2 holes. The instructions talked about elongating the holes on the skid plate, but it's not necessary on an FJ.

A lift will wear out your CV joints prematurely.

At the same time odds are less you'll damage your non-lifted rig off road, but you'll take your lifted rig further.

In either case, I doubt that it'll be around in 10 years with no troubles that were lift-related.

Other stuff breaks, too.

Not to start an arguement, but I have to disagree with your statement. After all of our testing, and running our lifts on IFS Toyota trucks we have never seen a broken CV. Our 99 Tacoma has 80,000 miles with different 3"+ lift combinations on it, and before last year when we had to replace an inner CV boot at 100k miles, we have never had any problems. It has had a tough life also..The angles on the newer Tacoma, 4Runner, and FJ are less severe, and we havent seen a single problem with any of those models yet.
If there are a whole bunch of photos posted everywhere online with broken parts on these vehicles, we have not found them...
I think I remember someone on TTORA posting a broken axle online years back that was related to a front locker, and abuse!

I have to agree with ToyTec - we've been installing all types of suspendion systems for over twenty years, and rarely do you see any problems with Toyota axle shafts, CV boots, etc. On Toyotas that were equipped with ADD
(Automatic Differential Disconnect), there were issues when shops tried to max out the coilover lift to 3" - the axle ends pulled out just enough to trigger the ADD sensor, and 4WD would not engage. As long as it is installed properly, and you don't get "as high as possible " fever, you'll be fine. And for the record, ANY modification has the possiblity of reducing the lifespan of other components - that's part of the trade off for improved performance.
