Alterntive Replacement WH/XH Front Diff Bush's I have come across some alternatives to the factory type front diff bush's **)
First type for the top 2 bush's. (are being used by a couple of forum members already) http://cdn3.volusion.com/fyanx.kxcxt...jpg?1430734355 http://trzmotorsports.com/wp2/?produ...ential-bushing http://www.highhorseperformance.com/..._p/700-105.htm Second type http://static.wixstatic.com/media/46...1.2_75_png_srz http://www.jeeperf.com/#!product-pag...9-8ff24434adf2 http://www.ebay.com.au/itm/05-10-Jee...AAAOSwDNdVqN0O http://www.ebay.com.au/itm/05-10-Jee...kAAOSwMmBVnp1A |
Any advantages to these over factory bushes? Are they cheaper/better/easier to fit?
Cheers, HB |
Supposed to be better but only real world use can tell you that.
I will fit the silver/black ones to the top of the diff & the orange/red (one with the bar through it) for the front support, waiting till after Xmas when the $$ are back. They are more expensive then the factory ones, 2 to 3 times more expensive! But if they are as good as they claim & you have changed these before you will happily pay the difference. Prick if a job. I have been told that it stiffens up the front end improving power transfer (less movement means power is transferred to the wheels more efficiently) The negative is supposed to be more vibration can be transferred due to the rubber compound not absorbing as much as stock ones. Reports from the American SRT8 forums is no different to slightly more vibration. http://www.cherokeesrt8.com/forums/a.../t-150402.html The reason to replace them is not so much the knocking & excessive movement that you get when they fail but the pinion alignment with the front prop shaft, alignment issues are the main reason the boot fails on the CV in the end causing CV failure :evil: I replaced all the diff bush's with factory ones & the CV, I still had a CV failure 30,000km later. |
Good finds thanks Clarky.
My last OEM replacements only lasted ~30kkm, and now well overdue for replacement. Think I might've stressed them when I had the diff hanging a few weeks after installing. I'll try the red (polyurethane I assume.) upper ones if you're gunna try the silver/black ones. |
Looking at the two threaded bushes ,how are they tightened up.? Doesnt seem to be any flats for spanner etc.

Contacted Jeeperf on installation details & they got back to me within the hour.
