Replaced pump, bled system, replaced seal, lowered the car and the seal blew again when i started it. I removed the radiator, blew compressed air through the return line and power steering cooler, no blockage. This is rediculous

system pressure should be 300psi or less with the wheels straight ahead...deadhead pressure spec is 1490 to 1590.
not sure where to go...if there are no restrictions in the hoses, cooler and the pump and rack are new. maybe bad new parts?Aftermarket parts or oem?

there is a recall for leaking ps hoses from fca for this model. if you want me to check if its open for your car pm me the last 8 of the vin.

I did a search thru some professional tech repair sites and did not find any occurrences.

One last brand new seal going in today, .010" adjustment to the pinion (hard to explain but it seems the seals seat on a fattened base circle of the pinion. If the pinion is pushed even .020" downward, the seal wont be seated) if this doesn't work, im getting a refund for the rack. I have a reeling the pinion isnt properly routing the pressure

Last attemp with new seal, new rack and pinion, new pump, prestone ps fluid, 100% power steering system removal and cleaning, new snap rings on pinion. Update in 2 hours or less. Heres a pic of the blown seal "new" when the rack and pinion i ordered came built.

that's a sector shaft seal...probably an aluminum body with a worn spool valve. hope you got a new unit not rebuilt.

Polished it up and put a new seal in, its holding for now, drove it to a shop to get another allignment, ill pist again if it blows. This seal is way tighter than the previous seals too, have a good feeling about it

Well friends... drove about 300 miles.. annnnddd seal blew again... ordering chrysler rack and pinion now, pretty sure that will sum it up, should have done so in the beginning. I guess i know now, absolutely dont ever trust aftermarket "remanufactured" ****... im so done with this car, but its only my fault for buying cheap stuff.

Default Peice of junk 2010 charger sxt 3.5l

Iím having the exact same problem. In January last year I replaced my rack and pump. One problem could be there is a filter in the bottom the the reservoir that can be clogged. Simply replace the reservoir on rockauto for 30 bucks. Thatís worked for me until the weather got cold and blew again. I think Iím on rack number 4, replaced the pump twice now cause I drove it home and burned the pump up because it happened while I was driving. All the previous times it would blow the return line off so I hose clamped the line and then the rack blew. Simply Iíve replaced every component pump, reservoir, rack, both lines. But the Oil cooler was not clogged when I blew air threw it. Car has about an 1/8 inch of dust on it cause Iím just ready to get it fixed and sold and wish I would have taken it to a shop to begin with but i do all my work myself cause I spend way to much on expensive tools to not do it lol

Finally someone who can relate..
remanufactured rack/core charge and over night ship: 450$
1st allignment:60$
2nd allignment: 127$( package deal to include unlimited alignments)
Seal kit: 60$ x2
Pump: 60$
Hoses and reservoir: 100$
Dodge inspection: 120$
Chrysler rack: 306$
Fluid refills:60$
in the end, i literally replaced every single component, and the issue has been fixed with the chrysler rack and pinion. When you study the components of rack and pinion type steering, the sector shaft/pinion/ thing (that slides into the rack with hellical teeth and has 4 internal seals and one large outer seal) has a huge responsibility. To handle and disperse properly up to 1500 psi hydraulic fluid, thats a huge amount.. my bad decision of not getting a chrysler part in the beginning was my fault. Also, make sure youre using the correct fluid, for my 2010 challenger rt, it requires AUTOMATIC TRANSMISSION FLUID +4. the autoparts stores kept going crazy and telling me im dumb until i made them look it up
