sir the estimate you got is correct. i went there a month ago and got exactly the same estimate. the good thing about cruven is their ball joint repair system. they will remake your ball joints, tie rod and rack end to make it last for years. i've learn their process because i was able to talk to the owner itself. mukhang totoo naman ang sinasabe nya regarding their suspension rebuilding system...
http://www.cruven.net/
the only thing i noticed with them is that may kamahalan ang mga replacement parts (for example - bushings) nila...
for example:
upper suspension arm bushing - 550/pc * 2 (one side only) = P1,100
+ upper ball joint repair = P350
total = P1,450
P1,450 mas mahal pa ito sa replacement part - brand: Optimum / Price: P1,300
***i am facing the same dilemma with regards to front suspension problems... ikaw ba papa rebuild mo sa cruven ang front suspension arm mo for total of P1,450 against sa pagbili mo ng whole replacement OEM assy for P1,300 (brand new)?
***here is my decision with this problem - Cruven is indeed an underschassis expert. no question about that, there are numerous reviews here in Tsikot and HCP. They are really good in repairing your underchassis.
What i Plan to do with my Honda EG Front suspension:
Buy OEM parts (here's the rundown)
-Lower suspension arm bushing (big) - 550/pc (c/o honda QAVE)
-buy whole upper arm assy - choice between Orig 555 (P3,000) or Optimum (replacement) Price: 1,300
-buy stabilizer links and stabilizer clamp bushings
**bibilin ko lahat ng bushings plus upper arm assy para sure ako na OEM talaga ang mabibili ko then dadalin ko sa knla para ma install nila at the same time ang papagawa ko lang sa kanila ay ang:
Tie Rod End P350 * 2 = P700
Rack End P350 * 2 = P700
Lower ball joint P350 * 4 = P1400
total is P2800
***in this way sigurado akong tatagal lahat ng bushings is at OEM specs. the only thing na papagawa ko sa kanila ay yung tie rod / rack end / ball joint rebuild which they do best. honestly mura yan (350 per repair).
lastly, one thing i learned about suspension / underchassis is that hinde pwede tipirin dahil pwersado ang mga parts na ito. meaning kelangan talaga orig part that will last for years and ilalagay mo dito since those joints are holding the weight of the car. so we better invest some cash on that
