I would like to start a discussion on dropping the front differential on IFS. More specifically, discuss these on Toyotas 4Runner 3<SUP>rd generation and <st1:City w:st="on"><st1:place w:st="on">Tacoma.</div>
While removing my Fabtech (Fox) shocks for rebuilding, the guys at ProTrux recommended me dropping the front differential. It was an easy install, just two spacers about 2” each. I have a picture on my phone to add here later.</div>
As a loan, they installed a TRD front shock coil over from a <st1:City w:st="on"><st1:place w:st="on">Tacoma. I did not realize until was too late in the trail, but it seems that I have less than stock clearance on the front now. I hit several rock and I easily passed before. Sure I had the Fabtech installed.</div>
- By dropping the front differential, one looses clearance?</div>
- The drop diff mod allows you to lower the angle of the half axels and release some stress on the CV. Therefore one can raise more the adjustable coil over. Right?</div>
- When I install my Fabtech again, and raise it above where it was before will I have more or the same clearance at the lower point bellows the front diff? I mean will really gain anything?</div>
- If I drop the diff ~2” and raise the suspension 2” what exact will I gain? One is in a straight line (drop diff) the other will be reflected as an angle on the suspension arms. </div>
- Am I adding any stress anywhere by lowering the front diff?</div>
I did not like much the mod. It is basically two aluminum cylinders. The original interface between the front diff and where it connects (name?) has a male / female setup. The spacers are flat. I wish they were machined to replicate the perfect fitting from the original setup. It seems that all the stress is being held by the bolts that go through the spacers. </div>
Please give me some feedback because I may remove the drop dif this week while re-installing the Fabtech shocks. Reliability is very important for me.</div>
I hope this discussion will be useful for others.</div>
Thanks in advance.</div>
