Too much backlash???

[Venom55]

I has an IRS from an '04 cobra installed in my '98 last week. i notice that there seems to be a bit more movement in the pinion flange but the technition said is was normal. now, if i'm sitting still and engage the clutch i get a loud "clunk" from the rear before i start to move. this also happens sometimes when i shift from gear to gear depending on how i shift. just seems like the gears should have a tighter tolerance. should i have the guys at the shop take the pumkin apart and check the backlash or is this normal for an '04?

Might want to ask in the Terminator forum...

Somehow I dont think its 'normal'...

The irs is know for the clunk. do a search in one of the othe cobra sections

could be from the mounting bolts that they had to revise. but if you've got play in the pinion flange then it sounds like the crush sleeve has been compressed could be from a bad install or if the rear was drag raced read: launched hard it could have crushed the collar

Backlash should be around .012" just pop the cover off get a dial indacater put it on one tooth keeping it strait as possible . Grab the ring gear and rock it back and fourth if it's over .014" then you have a problem.
